'Remarkable' explosions from colliding, dead stars could reveal the true expansion rate of the universeTwo conflicting methods to measure the expansion rate of the universe give different results, but researchers could resolve the disparity by watching merging neutron stars explode.

An ancient, ravenous black hole has been hiding an 11-billion-year-old galaxy in its glareA team of astronomers has used a tricky technique to study an ancient galaxy previously lost in the glare of a blazing quasar.

Mysterious source of water on the moon traced to Earth's magnetic shieldSome of the moon's surface water may have an Earthly origin, due to high-energy interactions between the sun and Earth's magnetic shield, new research suggests.
-
Astronomers measure dark matter 'haloes' around hundreds of ancient black holes for 1st timeStudying the mysterious form of matter around ancient quasar galaxies could have profound implications for our understanding of how the cosmos evolved.

NASA is hunting for life outside the solar system. Here's how."We aren’t going to see little green men but rather spectral signatures of these key chemicals, or what we call biosignatures."
-
Do black holes really suck in matter?Black holes can swallow matter, and they grow by accreting gas, dust and even the occasional star. But are they the vacuum-mouthed monsters they are often presented to be?
-
Perseverance rover spots a shark fin and crab claw on MarsIs something fishy happening on the Red Planet, or is it all in our minds again?
-
Will the sun ever become a black hole?Black hole sun, won't you come? It all depends on a star's mass before it dies.
-
Black holes keep 'burping up' stars they destroyed years earlier, and astronomers don't know whyYears after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.
-
Unknown ultra-light particles linked to dark matter could be found using atomic clocksThe use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab.
-
Baby sun-like star caught spewing out gamma-rays in cosmic 'tantrum' for the 1st time everThe discovery represents the first evidence that low-mass T.Tauri stars, which are less than 10 million years old, can emit gamma radiation.
-
Solar Orbiter probes how the sun generates solar windSo-called 'picojets' spotted by ESA's Solar Orbiter could be feeding high-speed gas outflows from the sun in the form of both energy and matter.
-
Neptune keeps growing enormous dark and bright spots, and scientists don't know whyScientists are still in the dark about what is causing a huge shadowy patch to appear against the blue background of Neptune’s sky.
-
Why do some stars fail to ignite?Also known as "failed stars," brown dwarfs are celestial bodies that sit on the boundary between gas giant planets and tiny stars.
-
Black hole 'seeds' discovered in the early universe for 1st time everThe puzzle of how supermassive black holes grew so large just after the Big Bang could soon be solved.
-
The Milky Way wasn't always a spiral —and astronomers may finally know why it 'shape-shifted'A century-old mystery of how galaxies change shapes has been solved by considering 'survival of the fittest' collisions between cosmic titans.
-
What's the largest planet in the universe?Astronomers have found planets that are twice as wide as Jupiter and more than 10 times as heavy, but there's a limit to how big planets can get.
-
Mysterious waves of magnetism may explain why the sun's atmosphere is hotter than physicists thought possibleThe sun's corona is 200 times hotter than its surface, defying models of stellar bodies. Now, this 80-year-old puzzle may finally have a solution.
-
Star-size black hole is emitting radio signals that scientists can't explainSuperfast changes to the intensity of a jet blasting out from a small black hole have been detected for the first time.
