If there is phosphine on Venus, there isn't much

In the absence of direct observations of extraterrestrial life, scientists often focus on searching for biosignatures, chemical by-products of life, that can be detected with remote sensing. Although Mars has received the ...

Cosmic 'dust' from supernovae hints at how stars are born

New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject ...

Image: A small sombrero for Hubble

NASA's Hubble Space Telescope has allowed astronomers to view galaxies of all shapes and sizes from nearly every angle. When a galaxy is seen edge-on, the mesmerizing perspective reveals a dazzling slice of the universe. ...

Celebrating Hubble's 32nd birthday with a galaxy grouping

The NASA/ESA Hubble Space Telescope is celebrating its 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called the Hickson Compact Group 40. This snapshot reflects a special moment ...

Image: Nebula churns out massive stars in new Hubble image

Stars are born from turbulent clouds of gas and dust that collapse under their own gravitational attraction. As the cloud collapses, a dense, hot core forms and begins gathering dust and gas, creating a protostar. This star-forming ...

Cloud-spotting on a distant exoplanet

An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision. A presentation by Dr. Romain Allart at the Europlanet Science ...

Sky survey reveals newborn jets in distant galaxies

Astronomers using data from the ongoing VLA Sky Survey (VLASS) have found a number of distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material within the past ...

Astronomers measure wind speed on a brown dwarf

Astronomers have used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) and NASA's Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf—an object intermediate in mass ...
