- by Stuart ClarkOne of the biggest mysteries in modern astronomy is how the Universe managed to grow enormous black holes so quickly.
- by Stuart ClarkA powerful wind in the early Universe may explain why some massive galaxies lived fast and died young by stopping forming stars far sooner than expected.
- by Stuart ClarkNew orbital mapping suggests Rosalind Franklin’s Oxia Planum landing site is part of a clay-rich region hundreds of kilometres wide, raising the possibility that it records a much larger watery episode in Mars’s early history.
- by Stuart ClarkThe Moon may preserve a record of the raw ingredients that helped life begin on Earth. New analysis of lunar samples returned by China’s Chang’e missions has revealed a diverse suite of organic compounds embedded within the soil.
- by Stuart ClarkAstronomers may not need to see the same dark matter signal everywhere in the Universe to confirm its existence. A new theoretical study suggests that dark matter could consist of more than one type of particle, potentially resolving a long-standing observational puzzle.
- by Stuart ClarkORLANDO, FLORIDA. I’m a space-crazed Canadian who has somehow seen 11 launches across four different rockets since 2009. I’ve witnessed missions with astronauts, interplanetary spacecraft and (inevitably) Starlink, across two continents. But Artemis II took me by surprise yesterday (April 1). The Space Launch System was so bright it was almost painful to look at. […]

- by Elisa NeckarBorn Aug. 1, 1818, Maria Mitchell was raised in the Quaker tradition, which allowed equal education for boys and girls. This, plus lessons from her father, afforded her the opportunity to become skilled in astronomy, mathematics, and navigation. After a brief stint as a teacher, she became the first librarian of the Nantucket Antheneum. SheContinue […]

July 31: Mercury brightening With the Moon rising later each night as it wanes, there’s a slightly longer dark window tonight for deep-sky observing. Let’s use it to track down NGC 6709, a lovely open cluster in the constellation Aquila the Eagle. Continue […]
- by Martin RatcliffeA partial lunar eclipse is visible across the U.S. this month, while a total solar eclipse occurs in Europe. Venus dominates after sunset, reaching 50% illumination. Most planetary activity is after midnight, as Saturn and Neptune rise in Pisces. The predawn hours reveal a fine conjunction between Jupiter and Mercury. And Mars crosses into Gemini,Continue […]
- by Alison KlesmanAlthough the early evening sky boasts only one naked-eye planet, quality more than makes up for the lack of quantity. Venus attains a splendid peak when it reaches greatest elongation Aug. 15. It then lies 46° east of the Sun and stands 30° high in the west an hour after sundown. The planet shines brilliantlyContinue […]
- by Brooks MendenhallStar formation in the nearby Andromeda Galaxy (M31) has been slowing down over the last 500 million years, according to a new study using Hubble Space Telescope data. The study was published July 27, 2026, in The Astrophysical Journal. Lead author Tobin Wainer, an astronomer at the University of Washington, and his team used dataContinue […]
- by Brooks MendenhallAstrophotography tends to blur the boundary between science and art. The incredible images from Hubble and JWST, for example, captivate us as much for their aesthetic beauty as for their data. Recently, a photography student blurred those lines even further, taking the concept of capturing the cosmos quite literally by creating images from film’s interactionContinue […]

- We have been watching asteroid (44) Nysa for well over a century without ever really knowing what it looks like. Now the sharpest images ever taken of it, from two of the largest telescopes on Earth, have revealed two deep valleys running right around its circumference and the team behind them think those are necks, […]
- The planet Neptune has 16 known moons, with its largest Moon, Triton, comprising more than 99.5 percent of the mass of all of them. Triton’s incredible size has led scientists to hypothesize it was a captured object originating from the Kuiper Belt, which wreaked havoc on Neptune’s original moon system upon its capture and subsequential […]
- Pluto’s moon, Charon, is one of the most unexplored (and arguably underappreciated) planetary objects in the entire solar system. This is primarily because it’s only been visited once by NASA’s New Horizons spacecraft during its famous Pluto flyby in July 2015. Despite this quick encounter, New Horizons beamed back troves of data regarding Charon that […]
- Given the state of our technology, it would take a spacecraft a ridiculously long time to reach even the nearest star in our galaxy. However, scientists continue to ponder ways in which we could achieve the dream of interstellar spaceflight. Here are a few of their best ideas.
- There are a number of things in the Universe that could wipe out life as we know it, but — for now, and for Earth — a blast from our galaxy's supermassive black hole isn't one of them. That's not to say that Sagittarius A* doesn't pose a danger. If it wakes up someday and […]
- Twenty five years ago a star in the constellation Puppis blew itself apart and then vanished behind a curtain of its own soot. Astronomers knew only that the explosion contained no hydrogen at all, which for the most abundant element in the universe is a very strange absence. Now the dust has finally thinned, and […]
