Hubble views dwarf galaxy LEDA 4216

This NASA/ESA Hubble Space Telescope image shows LEDA 42160, a galaxy about 52 million light-years from Earth in the constellation Virgo. The dwarf galaxy is one of many forcing its way through the comparatively dense gas ...

NASA volunteers find 15 rare 'active asteroids'

Some extraordinary asteroids have "activity"—comet-like tails or envelopes of gas and dust. NASA's Active Asteroids project announced the discovery of activity on 15 asteroids, challenging conventional wisdom about the ...

Citizen astronomers and AI discover 30,000 ring galaxies

Building on the synergy between citizen astronomer classifications and AI, astronomers have discovered approximately 400,000 spiral galaxies and 30,000 ring galaxies in data from the Subaru Telescope. This is the first example ...

Explaining a supernova's 'string of pearls'

Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research from ...

Astronomers propose a 50-meter submillimeter telescope

Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes ...

IceCube identifies seven astrophysical tau neutrino candidates

The IceCube Neutrino Observatory, a cubic-kilometer-sized neutrino telescope at the South Pole, has observed a new kind of astrophysical messenger. In a new study recently accepted for publication as an Editors' Suggestion ...

Webb finds ethanol and other icy ingredients for new worlds

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a variety of molecules, ranging from relatively simple ones like methane to complex compounds like acetic acid and ethanol, ...

Condor telescope reveals a new world for astrophysicists

A new telescope called the "Condor Array Telescope" may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical ...

Hubble sees spiral galaxy NGC 4423 edge-on

This NASA/ESA Hubble Space Telescope image shows NGC 4423, a galaxy that lies about 55 million light-years away in the constellation Virgo. In this image, NGC 4423 appears to have quite an irregular, tubular form, so it might ...

NASA's Roman team selects survey to map our galaxy's far side

NASA's Nancy Grace Roman Space Telescope team has announced plans for an unprecedented survey of the plane of our Milky Way galaxy. It will peer deeper into this region than any other survey, mapping more of our galaxy's ...
