A rare glimpse at a relatively nearby supernova offers clues to how stars die

Thanks to its home in the Pinwheel galaxy, a favorite of amateur astronomers, researchers have monitored SN 2023ixf since shortly after it exploded.

The black hole–powered jet in galaxy M87 is making stars explode

Hubble Space Telescope data show a surprising number of nova blasts along the jet of high-speed gas coming from the galaxy M87.

Vela’s exploded star is the highest-energy pulsar ever seen

A spinning dead star about 1,000 light-years away, in the constellation Vela, raises questions about how pulsars can emit such extreme radiation.

This ‘polar ring’ galaxy looks like an eye. Others might be hiding in plain sight

New images of two galaxies reveal what look like rarely seen rings of hydrogen gas nearly perpendicular to the galaxies’ starry disks.

Astronomers call for renaming the Magellanic Clouds

Explorer Ferdinand Magellan is not a fitting namesake for the pair of satellite galaxies of the Milky Way, a group of scientists argues.

Astronomy

Active supermassive black holes may be rarer than previously thought

A dearth of rapidly growing black holes in new James Webb telescope data raises questions about how these behemoths grow and influence their galaxies.

Astronomy

This extreme star might have huge tidal waves

Gravitational forces between two orbiting stars might be creating huge waves of plasma on one of the stars that break and crash to the surface.

JWST’s hunt for distant galaxies keeps turning up surprises

In its first year, the James Webb Space Telescope has found many galaxies from the early universe that are bigger, brighter and more mature than expected.

Meet Jane Rigby, senior project scientist for JWST and advocate for LGBTQ+ astronomers

Rigby, senior project scientist for the James Webb Space Telescope, believes being part of the LGBTQ+ community has made her a better astronomer.

Astronomy

Spiral galaxies might have been lentil-shaped before becoming starry whirls

By using black holes to track how galaxies merge and grow, an astronomer has proposed an update to the prevailing story of how galaxy shapes evolve.

The James Webb telescope may have spotted stars powered by dark matter

Three objects in the distant universe bear signs of hypothesized “dark stars,” researchers claim, though others say more definitive data are needed.

How an ancient solar flare illuminated the start of the Viking Age

Improved radiocarbon dating aided by a solar flare in the year 775 sheds light on the early days of Vikings and global trading in medieval times.
