AGB Star
Researchers from the University of Sheffield and Imperial College have discovered and old, evolved star interloping through a youn star-forming region (centre right). Astronomers previously thought that evolved stars cannot encounter young stars ad t...

Galaxy Ejecting Star
This shows a hypothetical spiral galaxy seen from an oblique angle. A red dwarf star has been ejected by the galaxy at high speeds and will wander the void between galaxies. Such objects are known as free-floating stars....

Sun Compared to Largest Star - Labelled
Diagram comparing the Sun with Stephenson 2-18. The latter is the current contender for the largest known star, a red hypergiant some 2150 times the diameter of the Sun. The Sun can fit into it 10 billion times!...

Gravity Waves from Colliding White Dwarfs
Two white dwarfs are approaching each other on an inbound spiral that can only result in destrucion, sending gravitational waves deep into the cosmos. They will soon collide to form a Type 1a supernova....

ZTF J0923+4236
The white dwarf shown in the illustration is one of several that an international team of astronomers has been studying. Called ZTF J0923+4236, the star exhibits a series of dips in its brightness. The team, led by Amornrat Aungwerojwit from Naresuan...

Kepler 444 - V2
Kepler-444 A is an orange main-sequence star twice the age of the Sun, an incredible 11 billion years old. Orbiting this are two red dwarfs (center, right) and five known planets. All planets orbit so close to their parent star that life as we know i...

Red Dwarf Flaring
Artwork of a red dwarf star emitting a stellar flare. A red dwarf is a small and relatively cool star on the main sequence, either late K or M spectral type. They range in in mass from a low of 0.075 solar masses to about 50% of the Sun and have a su...

Dormant Black Hole
Black holes normally reveal themselves in astronomy because they are surrounded by discs of gas, heated to high temperatures, stolen from nearby stars. The X-rays emitted from these accretion discs give away the black hole although it cannot itself b...

PNe - V5
Artwork of an imaginary planetary nebula. This is a glowing shell of gas cast off by a star near the end of its life. The star can be seen at the centre of the nebula. The Sun will one day form a planetary nebula, once its internal stock of hydrogen ...

Stolen Exoplanet
Scientists at Sheffield University, UK, used computational N-body simulations of star-forming regions to show that the 'BEAST' planetary systems - planets orbiting massive stars - can form from the capture of a free-floating planet, or the direct the...
