Webb image reveals young stars brewing in a nebulous cauldron

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 N159, located 161,000 light-years away in the Large Magellanic Cloud (LMC), one of […]

Webb captures stars in the early stages of life in a nearby stellar nursery

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 about 3,300 light-years from Earth in the constellation Cepheus. The image is already […]

Supermassive black holes ejected from galactic centers? Quasar survey supports decade-old prediction

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 identified in the data was predicted 10 years ago by members of the […]

Black hole observations uncover evidence of solar storm–like magnetic eruptions

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 3783, and the researchers’ findings were published in The Astrophysical Journal Letters.

Curtain-like plasma structures explain solar jets’ apparent spinning in simulations

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 form of warped, denser plasma sheets like pleated drapery.

There should be black holes in our neighborhood. Can we find them?

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 easy to spot for different reasons.

The sky in Van Gogh’s ‘Starry Night’ matches the predawn sky around July 22, 1889

New research published in Scientific Reports finds that the sky in Vincent van Gogh’s “Starry Night” (1889) matches, in both observation and shape, the predawn sky over Saint-Rémy around July 22, 1889. In the early hours of that period, a waning crescent moon, Venus and the Hyades star cluster in Taurus appeared close together. The […]

Are ‘mega-Earths’ real? Stellar activity may explain these oversized rocky worlds

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 stars. The paper was posted to the arXiv preprint server on Oct. 8. […]

NASA’s CASALS instrument bridges gaps in 3D maps of Earth’s surface

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 Spectrometry Lidar System (CASALS) could help researchers map the features of Earth’s surface […]

Hubble observations challenge supernova winds’ role in cosmic reionization

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.

Reexamined Viking 2 signal reveals possible marsquake from region active decades later

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 in 1976. Though the Apollo detectors proved a resounding success, Viking’s results on […]

Astronomers uncover the engine behind the most powerful stellar flares in the Kepler field

A new study led by researchers at the Konkoly Observatory of the HUN-REN Research Centre for Astronomy and Earth Sciences (HUN-REN CSFK) in Budapest has revealed what makes a distant red giant star the most explosively active in the entire Kepler field—and the answer lies in a surprisingly subtle interplay between a close stellar companion, […]

SpaceX turns a profit after a string of losses as its satellite and computer leasing businesses soar

SpaceX reported a bigger quarterly profit than expected Tuesday as its satellite communications operations and its business of leasing computing power to other companies boomed.

A magnetar can be born when two neutron stars touch

All neutron stars have intense magnetic fields. The typical magnetic field of a neutron star is about 100,000 times stronger than the strongest magnetic fields we can create on Earth. But about 1% of neutron stars have even stronger magnetic fields. Known as magnetars, their magnetic fields can be 1,000 times stronger than a regular […]

Rare solar radiation storm gives scientists clearest picture yet of flight risks

The most comprehensive data set ever collected from Earth’s atmosphere during a solar radiation event has highlighted the importance of better-coordinated radiation monitoring for aviation safety, according to new research led by the University of Surrey.
