Hubble Sees Crimson Cloud and Stars
Hubble Sees Crimson Cloud and Stars
Blue and white stars shine brilliantly against a crimson background of glowing gas in this July 3, 2026, image of stellar nursery LH 95 from NASA’s Hubble Space Telescope. LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. Low-mass infant s
Hubble details early galaxy transforming neighborhood 1.4 billion years after Big Bang
Hubble details early galaxy transforming neighborhood 1.4 billion years after Big Bang
Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of transforming
Image: Roman Telescope arrives at Kennedy Space Center
In this photo from June 21, 2026, NASA's Nancy Grace Roman Space Telescope arrives at the agency's Kennedy Space Center in Florida aboard NASA's Pegasus barge. After offloading and transportation to the spaceport's Payload Hazardous Servicing Facility, Roman will undergo processi
Euclid mission view of Milky Way's heart previews upcoming survey by NASA's Roman
A new look at the heart of our Milky Way galaxy by Euclid, an ESA (European Space Agency) mission with NASA contributions, overlaps with a region scientists will observe with NASA's Nancy Grace Roman Space Telescope, launching later this summer. This sneak peek gives astronomers
What are supermassive black holes? Everything you need to know about these mysterious obje
What are supermassive black holes? Everything you need to know about these mysterious obje
Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA's James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for the galaxy they're found in, challenging astronomers' understanding of these ob
Einstein Probe may have caught a black hole tearing apart a white dwarf for the first time
Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in its earliest moments, reveali
Ultraluminous X-ray source in Whale galaxy investigated for spectral and timing variabilit
Astronomers from Germany and Turkey have analyzed available data from various space telescopes to investigate an ultraluminous X-ray source designated X-4, which is located in the nearby galaxy NGC 4631. Results of the new study, published June 22 on the preprint server arXiv, yi
Chemically primitive galaxy from 13 billion years ago reveals record-low oxygen
An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this
Hubble spies ancient 'Chandelier Cluster' forming stars in two bursts
Hubble spies ancient 'Chandelier Cluster' forming stars in two bursts
The subject of today's NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more

NASA races to save Swift telescope from falling back to Earth with daring rescue mission
NASA is racing to save an aging telescope from falling back to Earth with a daring rescue mission. O recorte ajuda a contextualizar a pauta dentro de Agro.
Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years
Astronomers find an enigmatic source that is most likely a Little Red Dot in formation
Astronomers find an enigmatic source that is most likely a Little Red Dot in formation
Astronomers have, for the first time, found a source in the process of becoming a Little Red Dot, using the James Webb Space Telescope (JWST). Little Red Dots are likely early galaxies and some of the most intriguing objects found with JWST at high redshifts. The team, led by Kar
