Jan 26th, 2026 - Follow Earth on Google Small black holes in the early universe somehow ballooned to tens of thousands of times the Sun's mass within just a few million years – a pace that has long puzzled astronomers. Their rapid rise helps explain why massive black holes already appear in the universe's first chapters, but it also strains standard growth models that struggle to bridge such a large gap so quickly. New simulations now suggest those early black holes did not grow steadily, but instead ... [Read More]

Jan 26th, 2026 - This new map is not only the most detailed view of the universe's invisible scaffolding to date, it also allows astronomers to look deeper into cosmic history. Reading time 3 minutes —the invisible scaffolding thought to hold galaxies together—is arguably the most elusive substance in the universe. Nearly a century of research hasn't yet led to a confirmed direct detection , but scientists have learned to observe it indirectly . Now, one team has used those observations to produce ...

Jan 26th, 2026 - "These are just the difficulties of designing a spacesuit for the lunar environment." Crew members traveling to the lunar surface on NASA's Artemis missions should be gearing up for a grind. They will wear heavier spacesuits than those worn by the Apollo astronauts, and NASA will ask them to do more than the first Moonwalkers did more than 50 years ago. The Moonwalking experience will amount to an "extreme physical event" for crews selected for the Artemis program's first lunar landings, a ... [Read More]

Jan 26th, 2026 - Reading time 2 minutes NASA's Artemis 2 mission will send the first crewed spacecraft back to the Moon in over 50 years. As the Orion spacecraft makes its 10-day journey to the Moon and back, a group of volunteers on the ground will help track the crewed capsule on its journey into deep space using all kinds of equipment. NASA has selected 34 global volunteers to passively track Orion during the upcoming Artemis 2 mission , which is slated for launch as early as February 6. The list includes ... [Read More]

Jan 26th, 2026 - Follow Earth on Google Astronomers watching a seemingly ordinary, middle-aged star saw something unexpected unfold. For nearly nine months, the star faded to a small fraction of its normal brightness as a vast cloud drifted across its face – a cloud threaded with fast-moving, vaporized metals. The prolonged eclipse offered a rare look inside a mature planetary system that should have been quiet by now. Instead, the observations point to violent activity long after planets are thought to ... [Read More]

Jan 25th, 2026 - Three weeks after the Spirit rover touched down on Mars, its twin rover , Opportunity, landed on the opposite side of the Red Planet. Its descent was known at NASA as the "six minutes of terror," during which it had to employ a parachute and retrorockets to decelerate almost completely from 11,800 mph (18,900 km/h) before impacting the surface. The touchdown was successful, though: Encased protectively in airbags, Opportunity hit the surface, bounced 26 times, and came to rest. Completely by ... [Read More]

Jan 25th, 2026 - Follow Earth on Google Fast radio bursts are some of the strangest signals we pick up from space. They last just a few thousandths of a second, but they can outshine whole galaxies in radio light while they're happening. For years, one big question kept hanging around: what kind of object can make something that loud and fast – and sometimes do it again and again? Now, a long set of telescope observations has added a major piece to the puzzle. The key idea is simple. Some of these ... [Read More]

Jan 25th, 2026 - Follow Earth on Google Comets have a reputation for being cold, dirty snowballs lingering far from the Sun. Yet for years, astronomers have puzzled over one strange fact. Many comets contain crystalline silicates – minerals that form only under intense heat. That reality clashes with life in the deep freeze at the edge of a solar system. The puzzle has lingered for decades. How do materials that need extreme heat end up locked inside objects that spend most of their lives in bitter cold? ... [Read More]

Jan 24th, 2026 - Reading time 3 minutes It's difficult to overstate the significance of NASA's upcoming Artemis 2 mission . For the first time in over 50 years, astronauts will fly by the Moon on the first crewed test of the rocket and spacecraft that will eventually enable humanity's long-awaited return to the lunar surface. But Artemis 2 won't just test spaceflight systems and hardware. This mission will also put NASA's in-space science operations to the test. During their 10-day trip around the Moon, the ...

Jan 24th, 2026 - Inside an incredibly bright cluster of galaxies, a long-dormant supermassive black hole has come back to life. Radio images captured a one-million-light-year-long stream of star-forming particles and gas emanating from the black hole at the center of the galaxy J1007+3540—which apparently is erupting for the first time in about 100 million years. "Although some 'restarted' radio galaxies are known in the literature, J1007+3540 stands out," says lead study author Shobha Kumari of Midnapore ... [Read More]

Jan 23rd, 2026 - Sky This Week is brought to you in part by Celestron. Friday, January 23 Pluto reaches conjunction with the Sun at 5 A.M. EST. Also this morning, the Moon passes 4° north of Saturn at 8 A.M. EST and passes 4° north of Neptune at 11 A.M. EST. You can catch the trio in the southwestern sky after sunset. Earlier is better — around 6:30 P.M. local time, they are still 40° high, affording clear views of Neptune through binoculars or a telescope before it gets too close to the more ... [Read More]

Jan 23rd, 2026 - The biggest explosions in the universe, ranked The universe is exploding. Or parts of it are. The night sky may seem calm, even serene, but that masks events of a catastrophic and nearly unimaginable scale. Across the galaxy and even the cosmos itself, immense outbursts of energy occur that could easily vaporize our planet. Happily, space is vast, and the terrible distance between these events and us diminishes what we see to a faint glow—usually. It's very rare for our Earth to be ... [Read More]

Jan 23rd, 2026 - The northern sky's greatest galaxy gets its familiar name from the northern constellation where it resides, Andromeda the Princess. This star system is our nearest large spiral galaxy, and it sits at the far end of the Local Group of galaxies. Observations Observers have described M31 as something other than starlike as far back as 964. In that year, Persian astronomer Abdal-Rahman Al-Sufi called it a ''little cloud'' in his  Book of Fixed Stars . German astronomer Simon ... [Read More]

Jan 22nd, 2026 - Reading time 3 minutes On September 30, 2024, the Sun unleashed a powerful explosion, causing magnetic field lines to break and reconnect in a criss-cross pattern. A Sun-observing probe was there to watch it unfold, gathering unprecedented data that's helping scientists better understand the mechanism behind solar flares. Using the European Space Agency's Solar Orbiter spacecraft, a team of scientists discovered that solar flares are triggered by initially weak disturbances that grow more ... [Read More]
