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
Touch the Sun - Remember how Icarus wanted to touch the Sun, but met his demise instead? Well, scientists at NASA wanted to touch the Sun too, but unlike Icarus, they succeeded! Better yet, they are beginning to share what they learned by doing it! Before we get into all of that, let’s go back and start at the … Continue reading Touch the Sun
TRAPPIST-1 - You’ve probably heard that NASA has found a trove of “Earth-like” planets circling the TRAPPIST-1 system roughly 40 light years away, but just in case you haven’t, here’s a short video from NASA/JPL about the discovery.

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

Inter-satellite link (ISL) plays an essential role in current and future Global Navigation Satellite System (GNSS). A recent study, conducted by Wuhan University's GNSS Research Center and published in Satellite Navigation in May 2024, explored the significant effect of ISL data on the orbital characteristics of the BDS-3 MEO satellites.

It's tiny, but it's there. By now, we're all used to seeing amazing photos of Jupiter courtesy of NASA's Juno mission on a routine basis. Many of these are processed by volunteer "citizen scientists," and they show the swirling cloud-tops of Jove courtesy of the spacecraft's JunoCam in stunning detail.

In a quest to study the variety of stars in our galaxy, the Mauve mission has emerged to provide a stronger understanding of the characteristics of stars—including their magnetic activity, flare evolution, and influence on the habitability of neighboring exoplanets. Chuanfei Dong, an assistant professor of astronomy within Boston University's College of Arts and Sciences, is the lead Principal Investigator (PI) at BU for the Mauve mission.

May 2024 has already proven to be a particularly stormy month for our sun. During the first full week of May, a barrage of large solar flares and coronal mass ejections (CMEs) launched clouds of charged particles and magnetic fields toward Earth, creating the strongest solar storm to reach Earth in two decades—and possibly one of the strongest displays of auroras on record in the past 500 years.

Hubble views the dawn of a sun-like star
on May 15, 2024 at 8:43 pm
Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.

Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.

Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.

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.
