Laser-blasted plasma shows how instabilities could heat the sun's corona
From its visible surface, the sun radiates heat at a relatively cool temperature of 5,800 Kelvin. Yet within the thin outer layer of the sun's atmosphere known as the corona, electrons can reach temperatures of millions of ...
Stellar collisions may have been common when the universe was young
In our solar system's corner of the galaxy, stars rarely collide. It makes sense: Space is vast, and stars have room to roam. Even in most of the present-day universe, stellar collisions are rare. The James Webb Space Telescope, ...

JWST and ALMA reveal a dusty, rapidly growing black hole in the early universe
A new study reveals a dust-reddened quasar from a time when the universe was less than a billion years old. Located at a redshift of 6.5488, the object J1440+0019 contains a rapidly accreting supermassive black hole with ...
FAST and Arecibo point to possible dark galaxy with vast hydrogen reservoir
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 ...
Lumina simulation brings the early universe to life on a record-breaking scale
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 ...

Milky Way's disk grew 'upside down,' with younger stars forming in ever-thinner layers
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 ...

How flare ribbons reveal hidden solar explosions on the sun
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 ...

Stellar collision may explain why Orion Nebula's planet-forming disks appear younger than its stars
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 ...

Black holes spinning near maximum rate could split in two, calculations suggest
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 ...

ALMA spots 'dragon egg' that may represent the earliest stages of massive star formation
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, ...
NASA's Hubble charts path for Roman with gravitational lenses
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 ...

Autonomous triangular modules could build tomorrow's mega-observatories
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 ...

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 ...

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