Roman telescope aims to directly image exoplanets 1,000 times fainter than current limits

The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy

Liquid gallium experiment confirms key flow regime inside rapidly rotating stars and planets

Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes that occur there. Led by the University of California, Los Angeles (UCLA), an international research team has produced the first experimental verification of a theoretically predicted flow state deemed characteristic of the interiors of […]

Did ocean motion carve Enceladus’s tiger stripes?

Saturn’s moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers (1.2 miles) across and 130 kilometers (81 miles) long, the fissures spew water vapor and other materials […]

Why some lava-covered exoplanets retain atmospheres for billions of years

Stanford researchers have offered an explanation for why some sizzling, lava-covered worlds nestled tightly around their stars can retain their atmospheres. At such close quarters, intense stellar radiation should strip away a planet’s air.

Comet 220P McNaught puts on an encore performance

It has been a busy month for astronomy. In the midst of an eclipse season bookended by the total solar eclipse on Aug. 12 and the deep partial lunar eclipse coming up this week on Aug. 28, an outbound comet hanging high in the dawn sky just refuses to die: 220P/McNaught.

JWST reveals a race against time for forming planets

Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA’s James Webb Space Telescope (JWST) now offer a new view of how this gas escapes and how the process changes as young planetary systems develop.

SpaceX announces plans for $100 billion ‘spaceport’ in Louisiana

Elon Musk’s SpaceX announced plans Tuesday to build a $100 billion facility in the southern U.S. state of Louisiana to launch its anticipated Starship megarockets, currently being developed at the company’s Texas Starbase.

Gamma-ray signal could be long awaited evidence for WIMPs

Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never managed to detect the elusive substance directly.

Naked photobombing comet found in public image

Sometimes images are released before anyone realizes they have been photobombed, meaning something unexpected showed up in the background. A team of researchers found a naked photobombing comet in publicly available archival data from the Subaru Telescope, resulting not in mirth but in serious scientific discoveries.

Lunar soil reads as a cosmic time capsule for exploding stars

When a star reaches its final stages of life, it ends in a bright, powerful explosion called a supernova and scatters material across the universe. A new study led by a University of Hawai’i at Mānoa researcher has discovered that the moon’s mixed-up soil can be read as a cosmic time capsule for exploding stars. […]

New gallery of galaxies from NASA’s Chandra X-ray Observatory released

Galaxies are like cosmic gems, each with characteristics including size and shape that make them distinct. A new gallery released today from NASA’s Chandra X-ray Observatory and other telescopes displays a collection of galactic images that showcase this variety.

‘Now boarding’ … 240,000 miles from Earth, at the moon’s first airport

The moon’s getting its first airport, and it’s about to get busy. Within the next two decades, NASA’s planned Gateway—humanity’s first lunar spaceport—may become a bustling hub for Orion crew capsules, lunar landers, cargo vehicles and astronauts traveling between Earth, the moon and, eventually, destinations in the deep unknown.

The little red dots of our cosmos might hide something big

Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.

Setting limits on phase transitions in the dark energy era

The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand faster. Dark energy is thought to have become the predominant influence on the universe’s evolution around 3–4 billion years ago, at the […]

Meteorite dust holds records of magnetism that may have helped form the sun

Around 4.6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this “solar nebula” underwent a huge transformation, flattening into a disk of matter that then condensed to form the central sun and orbiting planets.
