Star Clusters Are Only the Tip of the Iceberg

Star clusters have been part of the Imaginarium of human civilization for millennia. The brightest star clusters to Earth, like the Pleiades, are readily visible to the naked eye. A team around ...

NASA's James Webb Telescopes Will Reveal Hidden Galaxies

Simulations show it's possible to distinguish host galaxy from quasars, although still challenging due to the galaxy's small size on the ...

The Mountains of Pluto Are Snowcapped, but Not for the Same Reasons as on Earth

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed ...

Astronomers Solve Dark Matter Puzzle of Strange Galaxy

Astronomers have found that the total number of globular clusters around Dragonfly 44 and, therefore, the dark matter content, is much less than earlier findings had suggested, which shows that this ...

Modelling Extreme Magnetic Fields and Temperature Variation on Distant Stars

New research is helping to explain one of the big questions that has perplexed astrophysicists for the past 30 years - what causes the changing brightness of distant stars called magnetars. Magnetars ...

The Black Hole Always Chirps Twice: New Clues Deciphering the Shape of Black Holes

Gravitational-wave scientists reveal that when two black holes collide and merge, the remnant black hole 'chirps' not once, but multiple times, emitting gravitational waves -- intense ...

Astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to ...

Studying the Sun as a Star to Understand Stellar Flares and Exoplanets

New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also ...

Astronomers Find X-Rays Lingering Years After Landmark Neutron Star Collision

It's been three years since the landmark detection of a neutron star merger from gravitational waves. Since that day, an international team of astronomers has been continuously monitoring the ...

In the Eye of a Stellar Cyclone

While on COVID lockdown, a college student has written a research paper on a star system dubbed one of the 'exotic peacocks of the stellar ...

A New Look at Sunspots

NASA's extensive fleet of spacecraft allows scientists to study the Sun extremely close-up - one of the agency's spacecraft is even on its way to fly through the Sun's outer ...

Spitzer Space Telescope Legacy

Scientists have provided an inventory of the major discoveries made possible thanks to Spitzer and offer guidance on where the next generation of explorers should point the James Webb Space Telescope ...

Scientists Study the Rugged Surface of Near-Earth Asteroid Bennu

As the days count down to NASA's OSIRIS-REx spacecraft's Touch-And-Go asteroid sample collection attempt, scientists have determined what the spacecraft can expect to return from the ...

Scientists Peer Inside an Asteroid

New findings from NASA's OSIRIS-REx mission suggest that the interior of the asteroid Bennu could be weaker and less dense than its outer layers -- like a crème-filled chocolate egg flying ...

Vaporized Metal in the Air of an Exoplanet

Researchers studied the atmosphere of the ultra-hot exoplanet WASP-121b. In it, they found a number of gaseous metals. The results are a next step in the search for potentially habitable ...

Signals from Distant Stars Connect Optical Atomic Clocks Across Earth for the First Time

Using radio telescopes observing distant stars, scientists have connected optical atomic clocks on different ...

Researchers Find 'Missing Link' Between Magnetars and Rotation-Powered Pulsars

Researchers have made observations of a new magnetar, called Swift J1818.0-1607, which challenges current knowledge about two types of extreme stars, known as magnetars and ...

Looking for Pieces of Venus? Try the Moon

A growing body of research suggests the planet Venus may have had an Earth-like environment billions of years ago, with water and a thin ...

Moon's Magnetic Crust Research Sees Scientists Debunk Long-Held Theory

New international research into the Moon provides scientists with insights as to how and why its crust is magnetized, essentially 'debunking' one of the previous longstanding ...

Explaining the Formation of a Hexagon Storm on Saturn

Researchers create a new 3D model that could explain the formation of a hexagon storm on Saturn -- a hurricane about 20,000 miles in ...
