How Scientists Read the Air of Distant Worlds: A Guide to Exoplanet Spectroscopy
Scientists analyze exoplanet atmospheres by studying how starlight filters through them during a transit, using spectroscopy to identify molecules based on specific absorption patterns. This technique allows astronomers to detect gases like water vapor and methane light-years away, revealing the composition of distant worlds.
NASA Roman Space Telescope Explores Universe
NASA's Roman Space Telescope, now successfully launched, is poised to send back 1.
JWST Spots Bright New Black Hole in Early Universe
Just 660 million years after the Big Bang, a newly discovered object, MoM-BH*-1, is producing roughly 100 billion times more energy than any known star could physically generate, according to ScienceD
James Webb Telescope Reveals 'Treasure Chest' with 70 Young Stars
The 'Treasure Chest' star cluster in the Carina Nebula, once thought to be a mere 100,000 years old, has been dramatically re-aged by the James Webb Space Telescope to a surprising 1.
James Webb Telescope spots supernova from universe's dawn
The universe was just 730 million years old when a massive star exploded, a cosmic event now confirmed by the James Webb Space Telescope.
James Webb spots mysterious Little Red Dots in the early universe
Over 300 mysterious 'Little Red Dots' (LRDs) have been spotted by the James Webb Space Telescope (JWST), appearing just a billion years after the Big Bang.
Euclid telescope reveals largest, most detailed image of Milky Way's galactic bulge
A single new image from the European Space Agency's Euclid telescope now reveals over 60 million stars in the Milky Way's galactic bulge, a view 270 times wider than what Hubble could capture in a sin
Quantum Foam: The Theory That Spacetime Itself Is Froth—and How Astronomers Test It
Quantum foam theory posits that spacetime is not smooth but a turbulent froth at the smallest scales, a concept tested by observing how high-energy light travels across vast cosmic distances. Astronomers use distant quasars and gamma-ray bursts to place limits on this theoretical 'foaminess' of spacetime.
Phobos: Rapid orbit, asteroid-like characteristics
Mars' moon Phobos bears a massive impact crater, a cosmic scar so severe it nearly shattered the moon.
Echo map hints at dark matter clusters by supermassive black holes
In five of 14 observed galaxies, a new 'echo mapping' technique has revealed mass around supermassive black holes increases in a way visible matter alone cannot explain, strongly hinting at dense dark
Summer Solstice brings Northern Hemisphere its longest day
In London, the summer solstice on June 21 delivers a mere two seconds more daylight than the day after, according to Explainingscience.
Total solar eclipse reveals rare sunset spectacle over Europe
From Spain's east coast, eclipse chasers will witness a totally eclipsed sun just a couple of degrees above the western horizon, minutes from sunset—a rare celestial alignment.
Supermassive black holes may be birthing millions of exoplanets
Millions of Jupiter-mass 'dust giants' and 'lava balls' could be forming tens of parsecs from supermassive black holes, challenging everything we thought we knew about where planets are born, Space re
Large Magellanic Cloud rips apart its smaller neighbor galaxy
Stars within the Small Magellanic Cloud are currently being pulled outwards from its core at an average speed of 17 kilometers per second.
Mallorca offers prime viewing for 2026 total solar eclipse
While millions plan to witness the 2026 total solar eclipse from Spain, only a sliver of coastline, like Mallorca's Playa de Palma, will offer the truly breathtaking sight: the sun just 2.
Scientists Discover Impossible Black Holes Reshaping Cosmic Theories
For the first time, physicists have observed a 'black hole triple' system where a central black hole devours a star every 6.
Webb telescope studies thousands of nearby star clusters
In a distant, strongly lensed galaxy, the James Webb Space Telescope has uncovered 'Firefly Sparkle' — 10 star clusters so massive and dense they exceed anything seen in our own Milky Way.
Rogue Star's Galactic Passage Shows Unexpected Stability
A star known as DESI-312 is currently hurtling through the galaxy at 314 kilometers per second.
