Universe is all of space and time[a] and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago, and the universe has been expanding ever since. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day. — Wikipedia

Universe (COSMOS: The SAO Encyclopedia of Astronomy)
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. — Wikipedia

The simulation below gives us an idea of what the Universe might look like on the largest scales. Stars form into galaxies, galaxies into clusters, and clusters into superclusters, which are represented by the brightest blue points. Between the clusters and superclusters exists the “Cosmic Web”, spindly filaments of galactic material and dark matter which stretch across the otherwise empty chasms. — European Southern Observatory

History
Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, calendrical, and astrological beliefs and practices of prehistory: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy. In some cultures, astronomical data was used for astrological prognostication. — Wikipedia

Private companies are getting better at launching more mass into space with larger rockets. But there is still a major constraint on the size of objects we can get into orbit—fairing size. This places physical constraints on the overall shape of what we can launch and severely limits the sizes of, say, a communications array or a power satellite. But a new paper from researchers at Nanjing University of Aeronautics and Astronautics and the Beijing Institute of Technology offers a solution—a […]
- Webb captures stars in the early stages of life...on October 22, 2026 at 5:40 pm
The NASA/ESA/CSA James Webb Space Telescope continues to reveal hidden parts of the cosmos with its advanced suite of infrared instruments. In a newly released image, Webb revealed many stars previously hidden by the dust clouds of NGC 7129, a stellar nursery about 3,300 light-years from Earth in the constellation Cepheus. The image is already improving our understanding of how new stars are born and evolve with time.

In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply N159, located 161,000 light-years away in the Large Magellanic Cloud (LMC), one of the satellite galaxies orbiting the Milky Way galaxy. This image spans about 230 light-years across.

By analyzing data on around 100,000 quasars, or extremely luminous galactic nuclei, researchers at Eötvös Loránd University (ELTE) have found statistical evidence that some supermassive black holes at the centers of galaxies are ejected from their positions after forming. The relationship now identified in the data was predicted 10 years ago by members of the same research group, Peter Raffai and Zsolt Frei, together with Zoltán Haiman.

Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more. The phenomenon was discovered in the vicinity of the black hole in the galaxy NGC 3783, and the researchers' findings were published in The Astrophysical Journal Letters.

Scientists have cracked a 178-year-old mystery surrounding a train delayed by a solar storm, revealing that the famous incident happened in 1848 rather than 1841. The discovery rewrites the early history of space weather and highlights a threat that still endangers modern power grids, satellites, and communication systems.

A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of weightlessness and handled simulated Martian gravity without major problems, offering new hope for future missions to the Red Planet.

NASA’s Perseverance rover has shattered a historic space exploration record, traveling farther across another world than any vehicle before it. Its advanced self-driving system helped it surpass Opportunity’s 28.06-mile record in just five and a half years, a feat that previously took nearly 15. Now, Perseverance is exploring some of the oldest rocks in the solar system, searching for clues about ancient Martian environments that may once have supported life.

1. The resources on this page are are organized by a classification scheme developed exclusively for Cosma.
2. The initial inspiration for the “astronomy” related pages was content encountered in the course PHYS 160 Exploring the Astrophysical World (taught by Thomas J. Moffett) at Purdue University. More content was added while designing and teaching Astronomy and Young Astronauts for gifted students in the Super Saturday/Summer program offered through the Purdue Gifted Education Resource Institute. The content has then been updated regularly since then.
