Hubble measures the distance to a supernova

Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a difficult one to complete.

How astronomers work out the size of the solar system

The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity ...

'Flares' and 'echoes' from the Milky Way's monster black hole

Michigan State University researchers have made groundbreaking discoveries about the supermassive black hole at the center of our Milky Way galaxy. These findings, based on data from NASA's NuSTAR X-ray telescope, were presented ...

Hubble views the dawn of a sun-like star

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in this new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable ...

New study reveals mystery of decaying exoplanet orbits

A new study led by researchers at Durham University has uncovered a novel mechanism that could solve a long-standing mystery about decaying planetary orbits around stars like our sun.

Hubble views ESO 185-IG013

This new NASA Hubble Space Telescope image shows ESO 185-IG013, a luminous blue compact galaxy (BCG). BCGs are nearby galaxies that show an intense burst of star formation. They are unusually blue in visible light, which ...

How NASA chases and investigates bright cosmic blips

Stephen Lesage's phone started vibrating just after halftime on Oct. 9, 2022, while he was watching a soccer game in Atlanta with a friend. When Lesage saw the incoming messages, the match no longer seemed important. There ...
