Unlocking the Universe: Exploring Astronomy in 3D

Explore the Universe With Astronomy 3D

Astronomy 3d is a powerful new way to experience the Universe. It enables you to explore and learn about planets, moons, stars, asteroids and even galaxies and their planetary nebulae.

Astrophysicist Nia Imara uses models that fit in her hand to unravel the structural complexities of star-forming clouds. The models reveal patterns from 2D dust maps that are often challenging to see in simulations.

3D Models

3D models help astronomers visualize complex structures and data. These models can include star systems, asteroids and comets, the Sun and the planets of our solar system, galaxy clusters, quasars, black holes, nebulae, and more.

This activity series takes participants through the basics of 3D modeling in astronomy using free, browser-based Tinkercad software. Students will learn to model simple shapes like disks and spheres, then move on to more complicated systems. Eventually, they can work with actual NASA data on exploding stars.

A new 3D model helps astronomers better understand the structures that form in molecular clouds—the giant clouds of gas and dust where stars are born. The model is a simulation of a star-forming region called M16, also known as the Pillars of Creation. It showcases the short-lived jets that emanate from the central star in this nebula, and the symmetric rings that appear as a result of those jets. These features would be difficult to discern with 2D projections.

3D Printing

Astronomers have been using 3D printers on the ISS to create tools and other parts that they can’t easily get from Earth. They are hoping that advanced manufacturing will help astronauts build habitats and land vehicles for long-duration missions and even planetary settlements.

The 3D printing process starts with a digital model, which is typically constructed in a CAD program. The data is then translated into the Stereolithography (STL) file format used by most 3D printers.

A prototype process was developed by Flatiron Institute researchers to turn astronomical images into a printable STL. They started with an image of a star-forming region called NGC 602, which was taken by the Advanced Camera for Surveys on the Hubble Space Telescope. The result is both visually stunning and scientifically illuminating. Among other things, the print shows protrusions, trenches and holes in the dust-filled region. It also reveals the structure of the star system Eta Carinae and the star-formation region known as the Pillars of Creation.

3D Animation

One of the most exciting aspects of 3D astronomy is that it can be used to show how objects in space change over time. This is especially useful in helping students understand concepts like orbits and the movement of celestial bodies.

Using the free astronomy software program 3DAstronomer, you can watch a simulation evolve in real time and observe its three-dimensional structure. You can even view the instantaneous orbits of objects as they change over time in view windows, and see how their positions relate to one another.

Finnish photographer J-P Metsavainio uses a technique that converts astrophotographs to artificial volumetric models — which he then renders as animations. He does this by analyzing the image for hints (e.g., the pillar structures in a nebula point to its center, reflection nebulas are in front). Then he sculpts the model with complex surface shapes. His work demonstrates that these types of images can be rendered in 3D with just some tweaking.

Virtual Reality

Several projects have used VR for interactive 3D visualisation of astronomical data. These range from 3D catalogues to cosmological simulations and spectral imaging.

For example, in the first project presented here, researchers using data from Chandra, Spitzer and other telescopes created a virtual 3D model of the supernova remnant Cas A. This revealed a structure that would have been difficult to detect with standard 2D models.

Another project uses a novel approach to immersive display of volumetric data in full dome theatres. The iDaVIE-d system displays the researcher’s view of the data in a virtual graphics window on the headset, which is then rendered in real time on the dome surface with the appropriate fisheye distortion to match the curved geometry. The theatre audience sees this projection from their reclining seats as they watch the VR researcher interacting with the spectral cube.

The IVL team has explored a variety of physics driven 3D datasets using this system, including the 2MRS redshift survey and a cosmological simulation of galaxy-galaxy gravitational interaction. These demonstrate the ability of VR to provide a more natural way of exploring and analysing dynamic data sets, compared with standard 2D visualisation.

The Life and Career of an Astronomer

What Does an Astronomer Do?

Astronomers observe and study celestial phenomena. They also work in offices and observatories. Their job responsibilities include doing scientific experiments and research, planning and writing proposals for funding, doing complex math calculations, designing and developing computer software that models data, etc.

Some astronomers do public outreach and write books for the general public. However, most of their time is spent doing research.


Astronomers are scientists who study the solar system, galaxies and other areas related to outer space. They work in universities, observatories and planetariums and often teach classes. They also work for government agencies, such as NASA and the Department of Defense.

The field of astronomy is highly competitive. Many astronomers spend 5-7 years in grad school, where they have tuition costs waived and earn a small stipend. After that, they may spend a few more years as postdoctoral researchers before finding permanent employment.

This type of job requires a lot of hard work and attention to detail. Astronomers must comb through a large amount of data and look for subtle shifts that may seem insignificant to the untrained eye. They also have to write reports and proposals for research funding. This can be a very challenging and rewarding career, but the pay isn’t great. Many astronomers will end up working for the federal government or private not-for-profit institutions.


Astronomers may work in universities, observatories and planetariums or in private industry such as software writing. They also work for government agencies such as the National Aeronautics and Space Administration (NASA) and the Department of Defense and at national laboratories like Los Alamos National Laboratory in New Mexico, the Goddard Institute in Maryland and Lawrence Livermore Laboratory in California.

Those who work for the government usually earn more than those who work in academia. In addition to their research responsibilities, astronomers who work for government agencies often act as consultants to NASA and serve on government panels in the sciences.

Other astronomers use their skills to teach in colleges and universities where they can share what they know about the universe with students and the public. They can also become writers of science fiction or nonfiction books aimed at the general population. In all cases, astronomers must be able to convey complex information clearly and succinctly in both written and verbal communication.


Astronomers can work in many different environments, including the private sector as software writers or technical advisers, as well as for universities and the government. They can also choose to specialize in areas such as cosmology or telescope design.

Working in astronomy is often highly competitive, and salaries are usually high. In fact, it is regarded as one of the top 10 highest-paying careers. However, it can be very stressful, particularly if your research is not progressing as expected. In addition, you may have to travel a lot for conferences and meetings with other astronomers from around the world.

Another aspect of the career that can be difficult is switching between different institutions. The typical career path from a PhD program at a university to tenured faculty typically takes more than 10 years and requires multiple relocations. This can be a huge financial sacrifice for some families and individuals. Astronomers also spend a large amount of time writing scientific papers and applying for grants to fund their research projects.

Work Environment

Astronomers are often employed by universities and other research centers. They may also work in planetariums and science museums or teach in secondary schools. Many astronomers do public outreach as well, giving multiple talks to the general public each year. They may also help to plan space missions for NASA and other organizations.

Working in this field can be quite a time commitment. It takes a while to make the transition from a grad student in a PhD program to an academic faculty member at a university and this can require moving around to different institutions several times. However, for those who are dedicated to the field, it can be a fulfilling career choice. Depending on the location, salary levels for this profession can be above average as well. This is especially true in places like San Mateo, California, and Green River, Wyoming where the average salaries for astronomers are higher than the national average.

Exploring the Universe: Astronomers, Astrophysicists, and Planetary Scientists

Astronomer Description

Astronomers spend a lot of time at observatories peering through optical, radio and digital telescopes. They also spend time analyzing and writing.

They also work with spacecraft and satellite manufacturers. They assist with planning space missions for organizations like NASA and help build better telescopes and other observational instruments.


Astronomy is the scientific study of objects in space, including planets, stars, galaxies and black holes. Astronomers use telescopes and other instruments to collect data and analyze information about these celestial objects. They also develop theories and models of these systems to explain their characteristics and processes.

Most astronomers specialize in one of two broad areas: observational or theoretical. Observational astronomers make direct observations of celestial bodies and use this information to build theories. Theoretical astronomers develop models or computer simulations of cosmic phenomena that cannot be observed directly.

For example, a radio astronomer studies cosmic microwave background radiation and the structure of galaxies using radio waves rather than visible light. This work helps scientists understand the conditions of the universe in the earliest stages of expansion.

Other important skills for astronomers include math, statistics and computer programming. They often collaborate with other researchers and engineers. They may also need to write proposals for observing time with telescopes or funding for research projects. The ability to communicate scientific concepts and data in a clear, concise manner is critical. A knowledge of the history of astronomy is helpful for understanding the evolution of the field. A special interest in a particular region of the galaxy or solar system is sometimes helpful as well.


Astrophysics is the branch of astronomy that focuses on the physical aspects of celestial bodies. It examines the origin, and the chemical and physical nature of heavenly bodies, as well as their interactions with each other and with interstellar space. The Sun, other stars, galaxies, nebulae, extrasolar planets and the cosmic microwave background are some of the subjects that are studied by astrophysicists. The properties of these objects are examined across the electromagnetic spectrum, including luminosity, density and temperature.

Astronomers study these objects using a wide variety of instruments and techniques. One of the most important instruments is a telescope, which allows scientists to gather data about a range of topics. Astronomers who focus on gathering this type of data are referred to as observational astronomers.

Other astronomers use computer models and mathematical equations to help predict the behavior of celestial bodies. They also look at how stars and other objects are born, grow and die. This helps astronomers to form a better understanding of the universe and our place within it. They also monitor space for any objects that might impact earth or deployed satellites, and they work with engineers to develop more powerful telescopes and observational instruments. The astronomers’ discoveries help to answer questions about our universe, such as how did it begin and what is its destiny?

Planetary science

The field of planetary science is a sub-discipline of astronomy and studies celestial bodies (including planets, their moons, rings, asteroids and comets) in the Solar System and beyond. It is a strongly interdisciplinary field that encompasses a range of other sciences including geology, chemistry and physics.

Planetary scientists are interested in the formation and evolution of planets, their moons and rings and other smaller bodies such as asteroids and comets. It also includes examining the origin and nature of extrasolar planet systems, or exoplanets, which are worlds that orbit stars other than our Sun.

Planetary scientists may study Earth analogues for the Solar System, including the effects of space weathering on lunar regolith. This is a process that erodes surface material as it is exposed to constant micrometeorite bombardment, high-energy particles and impacts. The discipline also focuses on planetary geodesy, which is the measurement and representation of the motions of a body in three-dimensional time-varying space. Planetary science is a rapidly growing area of research, with increased interest in planetary exploration and the discovery of exoplanets. Most planetary scientists are located in the astronomy, astrophysics or Earth sciences departments of universities or research centres. Alternatively, students can major in Earth science and then choose to focus on a specific sub-field of planetary science at the graduate level.

The Study of Celestial Bodies: Astronomy

Astronomy Root Word

Astronomy is the scientific study of celestial bodies, including stars and galaxies. It is also known as cosmology.

Scientists have observed the movements of celestial objects since ancient times. They combined this knowledge with their beliefs to predict future events on Earth (astrology).

During the 17th century, astronomy advanced significantly with the development of the telescope. This led to major discoveries in the field.


The study of celestial objects and events that occur outside the earth’s atmosphere. Astronomers use telescopes and other scientific equipment to observe and collect data about the universe.

The astronomy of stars is the science that describes their apparent positions and motions. It also explains their origins and chemical compositions. The word astronomy comes from two Greek words: astron, meaning star, and nomos, meaning law or system.

The astronomy of planets is the science that studies their movements and interactions with each other and other cosmic bodies. It includes the physics of stars, the formation of galaxies, and the life cycles of stars. Astronomy is the oldest of all sciences and has a history that dates back thousands of years. Astronomy has helped humans better understand our place in the universe and the forces that shape it. Astronomy is often (but not always) focused on very concrete, observable things, as opposed to cosmology, which is more concerned with the large-scale properties of the universe and theories like dark matter and dark energy.


Staring at stars and pondering their movements requires a person focused on detail and removed from the petty distractions of earthly life. Astronomers use large telescopes to track and study the energy emitted by stars and movement of planetary bodies. This highly cerebral field of study is also referred to as astrophysics or the study of celestial bodies.

An astronaut is a person trained to operate and work aboard spacecraft. NASA and other space agencies recruit candidates for the astronaut program, who undergo grueling training programs before they’re assigned to a mission. Astronauts are figures of awe and admiration, and it’s not uncommon for people to have aspirations of becoming one someday.

The word astronaut comes from the Greek astron and Latin nautes. It was adopted by NASA in 1961 to describe those who would participate in space exploration missions. The Russian equivalent is cosmonaut, which comes from the root kosmos. These explorers are often trained military personnel, but recent accessibility of space travel has allowed civilian astronauts to fly into orbit.


An asteroid is a rocky or metallic object in space that circles the Sun. It’s what’s left over from the material that made the planets in our solar system billions of years ago. Asteroids can vary in size, from a pebble to a dwarf planet larger than Jupiter. Most are found in the asteroid belt, which lies between Mars and Jupiter.

Astronomers have a lot of fun naming asteroids. Some of them have whimsical names, such as one named after Mr. Spock from Star Trek, and others are named after late rock musicians and celebrities.

The prefix astro comes from the Greek word astron, meaning “star.” It’s used in words that relate to stars and celestial bodies, as well as activities, such as spaceflight, that take place outside the Earth’s atmosphere. Some examples include astronomy, astronaut, asteroids, and astrocytes. Astronomy is a scientific discipline that has a rich heritage that continues to inspire generations of scientists.


Astrocytes are star-shaped glial cells that perform many different functions including structural support, regulation of the chemical environment and neuronal metabolism. They also engulf CNS synapses to eliminate cellular debris through MEGF10 and MERTK phagocytic pathways. During brain development, astrocytes help to provide guidance cues for neuronal cell migration and expansion from progenitor cells in the subventricular zone (SVZ).

Astrocytodes communicate with neurons through gap junctions and release various substances including calcium, ions, prostaglandins and nitric oxide. They also regulate local blood flow in the central nervous system (CNS) and are the main glucose storage units of the brain.

Unlike other cells, astrocytes have high-affinity uptake systems for glutamate and gamma-aminobutryic acid, which may explain why they are able to control synaptic transmission. They can also rapidly clear away chemical messengers from the synapse, called neurotransmitters, to reset the synapse for the next transmission. This is important, because if the neurotransmitters lingered too long they would interfere with communication between neurons.
