Astrophysicists detect neutron star merger for the first time in millimeter light

Short-duration gamma-ray bursts only last a fraction of a second, making them difficult to detect. Astrophysicists detected the burst with X-rays and then identified its...

Scientists capture explosive neutron star merger for the first time in millimeter light

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger...

Scientists reveal the distribution of dark matter around galaxies 12 billion years ago

Scientists have investigated the nature of dark matter surrounding galaxies seen as they were 12 billion years ago, billions of years further back in...

Scientists discover a super-earth near the habitable zone of a red dwarf

A super-Earth planet has been found near the habitable zone of a red dwarf star only 37 light-years from the Earth. This is the first...

Planet 9 is running out of places to hide

We have a pretty good idea of what lurks within our solar system. We know there isn’t a Mars-sized planet orbiting between Jupiter and Saturn,...

Citizen astronomer helps find more than 30 ultracool dwarf binary systems

A citizen astronomer participating in the U.S. National Science Foundation-supported Backyard Worlds program examined archival data provided by the Community Science & Data Center...

Earth’s magnetic field almost completely collapsed 550 million years ago

More than half a billion years ago, Earth experienced an almost-complete collapse of its magnetic field. It began in the early Cambrian period. Then, after...

Scientists discover places on the moon where it’s always ‘sweater weather’

People could potentially live and work in lunar pits and caves with steady temperatures in the 60s. Future human explorers on the moon might have...

Scientists discover the heaviest neutron star to date

A dense, collapsed star spinning 707 times per second — making it one of the fastest spinning neutron stars in the Milky Way galaxy...

How will JetBlue’s $3.8B acquisition of Spirit Airlines affect consumers?

After a months-long bidding war, JetBlue Airways has agreed to buy Spirit Airlines for $3.8 billion. The deal, which was announced Thursday, would create the...

Scientists find remnants of an ancient galaxy at the edge of Andromeda

An amateur astronomer examining archival data processed by the Community Science & Data Center tipped off astronomers about a smudge of interest in an...

Astronomers find origins of mysterious gamma-ray bursts

Several mysterious gamma-ray bursts appear as lonely flashes of intense energy far from any obvious galactic home, raising questions about their true origins and...

Scientists reveal the hot Jupiter’s dark side for the first time

The planet’s night side likely hosts iron clouds, titanium rain, and winds that dwarf Earth’s jetstream. MIT astronomers have obtained the clearest view yet of...

Scientists perform the coldest reaction in the known universe

In temperatures millions of times colder than interstellar space, Harvard researchers have performed the coldest reaction in the known universe. But that's not all....

Astronomers pinpoint the best place on Earth for a telescope

Dome A, the highest ice dome on the Antarctic Plateau, could offer the clearest view on Earth of the stars at night, according to...

Scientists find the major producers of lithium in our galaxy

Scientists, led by astrophysicist Professor Sumner Starrfield, have determined that a class of stellar explosions, called classical novae, are responsible for most of the...

Scientists discover a massive ice giant exoplanet

In our solar system, the “ice giants” Neptune and Uranus are far less dense than rocky Venus and Earth. But astrophysicists on NASA’s TESS...
