Dark matter may have started hot and cooled during reheating after the Big Bang.
A new study finds dark matter could have formed at near light speed and still cooled enough to build galaxies.

Artist's impression of a forming galaxy cluster in the early universe: radio jets from active galaxies are embedded in a hot intracluster atmosphere (red), illustrating a large thermal reservoir of gas in the nascent cluster.

By merging two spacecraft views, scientists tracked NOAA 13664 for 94 days and learned how its magnetic chaos fueled major solar storms.

Artist's concept shows the red supergiant star Betelgeuse and an orbiting companion star. The companion, which is orbiting clockwise from this point of view, generates a dense wake of gas that expands outward.

Meteorite chemistry shows which primitive asteroids may hold usable metals or water, and why most space mining remains difficult.

JWST has revealed a black hole so massive, and so star-poor, that it bends standard cosmic origin stories.
SpaceJWST discovers a massive primordial black hole that may have formed before starsJoseph Shavit
This image shows the location of Cloud-9, which is 14 million light-years from Earth. The diffuse magenta is radio data from the ground-based Very Large Array (VLA) showing the presence of the cloud. The dashed circle marks the peak of radio emission, which is where researchers focused their search for stars.

A rare cosmic alignment reveals a rogue planet drifting alone through the Milky Way
SpaceGravitational lensing helps astronomers determine the true mass of a rogue planetJoseph Shavit
New research finds that two massive, hot stars swept past the Sun about 4.4 million years ago, blasting nearby gas clouds with radiation and leaving a lasting imprint on the space surrounding your solar system.
SpaceTwo blazing stars once raced past the Sun and reshaped our solar systemJoseph Shavit
Artist's view of WASP-107b. The planet’s low density and the intense irradiation from its star allow helium to escape the planet and form an asymmetric, extended, and diffuse envelope around it. Infrared observations with the JWST satellite have enabled the observation of this phenomenon.

An international team of researchers used the European Space Agency's XMM-Newton and XRISM, a JAXA-led mission with ESA participation, to uncover and study a never-seen-before blast from a supermassive black hole. The gravitational monster whipped up powerful winds, flinging material out into space at eye-watering speeds of 60 000 km per second.

Hubble imaged a record-size protoplanetary disk with one-sided filaments and turbulent “wisps,” reshaping ideas of planet formation.

Laboratory tests show that small amounts of silicon and carbon mixed with iron may explain why seismic waves travel unevenly through Earth’s inner core.

An artist’s rendering shows the rare galaxy system J1219+1035, where three galaxies are in the process of merging. At their cores sit three actively feeding, radio-bright supermassive black holes, with powerful jets illuminating the gas around them.
