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

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

Exoplanet Junket - This week NASA released a new project that they’ve dubbed the Exoplanet Travel Bureau. The core of the project consists of a set of interactive 360° images that show “imagined” surfaces of five exoplanets (TRAPPIST-1e, Kepler-16b, Kepler-186f, PSO J318.5-22 and HD 40307 g). Here are three articles about the experience. This Brilliant Interactive From NASA … Continue reading Exoplanet Junket
Moon’scapes - There’s no denying that it’s been a rough week for many Earthlings. On the other hand, it’s been a great week for anyone who spends their time more preoccupied with the Moon than with more earthly concerns. That’s because there’s a treasure trove of news about our lunar realm. For example, NASA’s Goddard Media Studios … Continue reading Moon’scapes
Space Cadet Academy - Confession — I’m a major space cadet! I mean this in an older, positive sense of the word, which is that I’m a “space enthusiast.” That’s why I really get into updating the pages on Cosma having to do with space. Things got a little out of hand this time, though. I began just like … Continue reading Space Cadet Academy

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

Technical trials for easing the (cosmological)...
on April 19, 2024 at 1:19 pm
Thanks to the dizzying growth of cosmic observations and measurement tools and some new advancements (primarily the "discovery" of what we call dark matter and dark energy) all against the backdrop of General Relativity, the early 2000s were a time when nothing seemed capable of challenging the advancement of our knowledge about the cosmos, its origins, and its future evolution.

on April 19, 2024 at 12:26 pm
Earth's magnetic field protects us from the dangerous radiation of space, but it is not as permanent as we might believe. Scientists at the European Geosciences Union General Assembly present new information about an 'excursion' 41,000 years ago where our planet's magnetic field waned, and harmful space rays bombarded the planet.
Study suggests Io's volcanoes have been active...
on April 19, 2024 at 12:22 pm
A team of geologists and planetary scientists from the California Institute of Technology, the University of California Santa Cruz, New York University, and NASA Goddard Space Flight Center reports evidence that Io's volcanic activity has been ongoing since the beginning of the solar system. In their study, published in the journal Science, the group studied sulfur isotopes in Io's atmosphere to determine how long the moon has been volcanically active.
Unraveling water mysteries beyond Earth:...
on April 19, 2024 at 8:50 am
Finding water on distant planets and moons in our solar system is a challenge, especially when the instrument is thousands of kilometers away from the surface, but scientists presenting at the European Geosciences Union General Assembly describe how ground-penetrating radar is used to discover bodies of water below the surface of distant planets and they are on their way to Jupiter.

on April 18, 2024 at 7:28 pm
As the lunar exploration mission evolves from exploration to construction and utilization, in situ lunar construction becomes an imperative requirement. The key is regolith solidification and formation, aiming to maximize local resource utilization while minimizing transportation and maintenance costs.

Astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. The findings suggest that this brown dwarf might generate aurorae similar to those seen on our own planet as well as on Jupiter and Saturn.

Scientists have developed a new method using knot theory to find the optimal routes for future space missions without the need to waste fuel.
No gamma rays seen coming from nearby supernova
on April 16, 2024 at 4:53 pm
A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

on April 16, 2024 at 3:59 pm
Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.

Physicists solve a puzzle linked to JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age.

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.
