Artist’s concept illustrating Supernova 1987A as the powerful blast wave passes through its outer ring and destroys most of its dust, before the dust re-forms…
Artist impression of Orion Source I, a young, massive star about 1,500 light-years away. New ALMA observations detected a ring of salt — sodium chloride,…

False-color image of V883 Ori taken with ALMA. The distribution of dust is shown in orange and the distribution of methanol, an organic molecule, is…
A study using Chandra, XMM-Newton and Sloan Digital Sky Survey (SDSS) data suggests that dark energy may have varied over cosmic time. This artist’s illustration…
The stellar wind from a newborn star in the Orion Nebula is preventing more new stars from forming nearby, according to new research using NASA’s…
Beyond Neptune, there is a large disc of small objects, called the Kuiper Belt and beyond that is the Oort cloud, home of the comets.…
The Hubble Ultra Deep Field of galaxies. A new study of the star formation activity in 179 of the galaxies in this image including many…
This is an artist representation of the hypernova. The interaction of the jet with the outer layers of the star forms a cocoon that surrounds…
Illustration of Gamma-ray burst models. Left: Merger of two neutron stars (or a black hole and a neutron star) to produce gravitational waves; Right: Gamma-ray…

Illustration of a white dwarf, the dead remnant of a star like our Sun, with a crystallised, solid core. White dwarfs are the remains of…
An X-ray/infrared composite image of G299, a Type Ia supernova remnant in the Milky Way Galaxy approximately 16,000 light years away.NASA/Chandra X-ray Observatory/University of Texas/2MASS/University…
This artist’s impression shows hot gas orbiting in a disk around a rapidly-spinning black hole. The elongated spot depicts an X-ray-bright region in the disk,…
Researchers have discovered the brightest quasar yet known, detected from the period when the universe’s star-making hydrogen gas became ionized, known as “reionization.” The international…
A computer simulation of a galaxy (left); the same galaxy adjusted to appear as it might in an observation by the Sloan Digital Sky Survey…
Star formation in tiny dwarf galaxies can slowly “heat up” the dark matter, pushing it outwards. The left image shows the hydrogen gas density of…
Hubble Space Telescope image representing a merger between two galaxies (M51a and M51b) similar in mass to the Milky Way and the Large Magellanic Cloud.…
At left is a composite of two images taken by New Horizons’ high-resolution Long-Range Reconnaissance Imager (LORRI), which provides the best indication of Ultima Thule’s…
