Astronomers have found a vast reservoir of hydrogen with something conspicuously missing: detectable starlight. The object, called AGC 322753, contains roughly 2 billion times the sun's mass in neutral hydrogen, a potential supply of material for making stars. Its radio signal suggests…
Before astronauts return to the lunar surface, NASA will first conduct one of the most ambitious and complex test missions in the agency’s history. Launching in 2027, Artemis III will send NASA astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and ESA (European Space Agency) astronaut…
NASA’s Neil Gehrels Swift Observatory has ended its science mission now that the spacecraft is orbiting less than 171 miles (275 kilometers) above Earth’s surface. The greater atmospheric drag at this height prevents the satellite’s telescopes from steadily gazing at their astronomical targets. Swift conducted…
The James Webb Space Telescope (JWST) and Nancy Roman Space Telescope are revealing the universe's earliest chapters in detail. To help astronomers understand what they are seeing, researchers at the Center for Astrophysics | Harvard & Smithsonian have developed "Lumina," one of…
The Milky Way is home to hundreds of billions of stars arranged in a glorious spiral pattern. But beyond the obvious spiral, our galaxy has other physical characteristics. It's divided into a galactic bulge, a galactic disk and a galactic halo.
Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their business. But the sun…
NASA is moving fast on its plans to build a moon base and return astronauts to the lunar surface in as little as two years.
Establishing a long-term presence on the moon will require solving challenges that are easy to overlook on Earth. Lunar temperatures, for instance, can vary from hundreds of degrees below zero to boiling, making effective insulation essential for lunar habitats.
The Orion Nebula is a large star-forming region visible to the naked eye. Some of the young stars in the nebula are surrounded by disks of gas and dust in which planets form. Radiation from the massive central star, 1 Ori C1…
Two black holes can collide and merge into one. But could the opposite happen: could a single black hole split into two smaller ones? That question is explored in a new theoretical study: "When Black Holes Admit Pair-of-pants Topologies," published in the…
Astronomers identified an exceptionally tiny core that may represent an early stage in the formation of a massive star. Located in an infrared-dark area called Dragon Cloud, the core is nicknamed the "dragon egg." The paper, accepted for publication in Astronomy &…
Do cosmic radiation doses near the moon differ significantly from those received by astronauts in low Earth orbit? Experimental lithium fluoride detectors, installed aboard the Orion spacecraft during the Artemis I mission, have now made it possible to obtain preliminary estimates.
With a successful Mars gravity assist in its rearview mirror, NASA's Psyche spacecraft has fired up its thrusters and is accelerating toward the metal-rich asteroid of the same name. During the first leg of its journey, following an October 2023 launch, the…
A sweeping barred spiral galaxy marks the spot in this image, but the real treasure is the gravitational lens in the lower-right corner, where a distant background galaxy is being magnified and distorted by the gravity of a closer galaxy.
In the deepest region of the Earth's mantle, just above the core, much of the material consists of crystals of magnesium oxide. In larger rocky exoplanets called super-Earths, the higher pressures in the lower mantle may drive magnesium oxide to transform into…
Private companies are getting better at launching more mass into space with larger rockets. But there is still a major constraint on the size of objects we can get into orbit—fairing size. This places physical constraints on the overall shape of what…
The NASA/ESA/CSA James Webb Space Telescope continues to reveal hidden parts of the cosmos with its advanced suite of infrared instruments. In a newly released image, Webb revealed many stars previously hidden by the dust clouds of NGC 7129, a stellar nursery…
In this Picture of the Month from the NASA/ESA James Webb Space Telescope, we visit a turbulent cauldron of star formation to see what is brewing inside dense clumps of gas. This is a star-forming region named LHA 120-N 159, or simply…
By analyzing data on around 100,000 quasars, or extremely luminous galactic nuclei, researchers at Eötvös Loránd University (ELTE) have found statistical evidence that some supermassive black holes at the centers of galaxies are ejected from their positions after forming. The relationship now…
Technion researchers have presented evidence for the existence of solar-storm-like outbursts near supermassive black holes, which can be a million times larger than the sun or more. The phenomenon was discovered in the vicinity of the black hole in the galaxy NGC…
Scientists doubling as art detectives have traced Vincent van Gogh's "The Starry Night" to a celestial scene that suggests a new date for one of the world's most famous paintings.
Scientific estimates show that there should be between about 100 million and 1 billion stellar-mass black holes in the Milky Way. But they aren't easy to locate. They're not like supermassive black holes (SMBH) at the centers of galaxies. Those are usually…
An international team of scientists from the University of Sheffield and the Indian Institute of Astrophysics, led by a postdoctoral research fellow from the University of Newcastle, Australia, has discovered that solar jets called spicules, which are 6–8 Mm long, take the…
A new study suggests that some of the heaviest rocky planets ever reported may not be as heavy as they look. These so-called 'mega-Earths,' rocky planets weighing more than about 10 Earths, could be an illusion created by activity on their host…
A team of researchers at NASA's Goddard Space Flight Center (GSFC) has developed a new instrument designed to eliminate blind spots between lines of lidar data on Earth's surface. Built with support from NASA's Earth Science Technology Office (ESTO), the Concurrent Artificially-intelligent…
An international team of researchers, including members from the University of Michigan, has revealed surprising results that could rewrite our understanding of a key transition in the early universe.
Earthquakes and the seismic waves they generate provide some of the best clues to Earth's interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking Mars landers, which reached Mars…
