A rare white dwarf merger remnant emerges in ultraviolet light, revealing thin layers of hydrogen and helium stripped away ...

The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another ...

Stellar Development Foundation chief product officer Tomer Weller joins CoinDesk Live at Consensus 2025 to discuss Stellar's recent growth and the evolution of the network. Plus, their long ...

Hayashi's contributions include the discovery of the Hayashi phase, a crucial period in stellar evolution characterized by high brightness and activity.

“Black holes this massive are forbidden through standard stellar evolution models.” To form this black hole, the two black hole predecessors likely had to measure around 100 and 140 times the ...

Astronomers have confirmed the existence of a companion star in a tight orbit around Betelgeuse, resolving a long-standing mystery about the star’s varying brightness.

Trans-Neptunian objects (TNO) are some of our solar system's lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets orbit the sun at a ...

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

Merger of two massive black holes is one for the record books The event resulted in a new black hole with a mass 225 times larger than our Sun.

The Hubble Space Telescope searches the universe to understand how planets, stars, and galaxies form. Recently, it captured this image of a nebula known as GN 04.32.8 within a larger stellar ...

The Hubble Space Telescope spies a stellar nursery in the Taurus Molecular Cloud nebula.

Knowing stellar ages is necessary to understanding not only how stars work, but also modeling how exoplanets form and evolve, and learning about the history of the evolution of our own Milky Way ...
