Astronomers trace a star’s three-year infrared glow to black hole birth

In 2014, a NASA telescope observed that the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around three years before fading dramatically and disappearing, leaving behind a shell of dust. Although a telescope captured the phenomenon at the time, it […]

Living in space can change where your brain sits in your skull: New research

Going to space is harsh on the human body, and as a new study from our research team finds, the brain shifts upward and backward and deforms inside the skull after spaceflight.

Decoding China’s new space philosophy

A major theme in communist governments is the idea of central planning. Every five years, the central authorities in communist countries lay out their goals for the country over the course of the next five years, which can range from limiting infant mortality to increasing agricultural yield. China, the largest current polity ruled by communists, […]

NASA moon mission spacesuit nears milestone

The next-generation spacesuit for NASA’s Artemis III mission continues to advance by passing a contractor-led technical review, as the agency prepares to send humans to the moon’s South Pole for the first time. Testing is also underway for the new suits, built by Axiom Space, with NASA astronauts and spacesuit engineers recently simulating surface operations […]

Hunting dark matter ‘stars’ that mimic black holes

Hypothetical dark matter stars known as “boson stars” could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a strange event was observed in the depths of space. Called GW190521, the event sent out gravitational waves—invisible ripples in the universe—that were picked up […]

New astronauts launch to the International Space Station after medical evacuation

A new crew rocketed toward the International Space Station on Friday to replace the astronauts who returned to Earth early in NASA’s first medical evacuation.

A ‘ring of fire’ solar eclipse will dazzle people and penguins in Antarctica

The first solar eclipse of the year will grace Antarctica, and only a lucky few will get to bask—or waddle—in its glow.

Europe’s Ariane 6 to launch Amazon constellation satellites into orbit

An enhanced version of Europe’s Ariane 6 rocket will blast off Thursday to launch 32 satellites into orbit, forming part of the Amazon Leo network, which it hopes will rival Elon Musk’s Starlink.

Hubble captures light show around rapidly dying star

This stunning image from NASA’s Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation Cygnus, the Egg Nebula features a central star obscured by a dense cloud of dust—like a “yolk” nestled within a dark, opaque […]

Chang’e-6 samples constrain lunar impact flux and illuminate early impact history

Scientists from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (CAS), the CAS Aerospace Information Research Institute, and other institutions, have revised the decades-old lunar crater chronology model, using samples collected from the far side of the moon by China’s Chang’e-6 mission and complementary remote sensing imagery.

Discovery of a possible pulsar in the Milky Way’s center could enable unprecedented tests of General Relativity

Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of civilizations beyond Earth, have published new results from the Breakthrough Listen Galactic Center Survey, one of the most sensitive radio searches ever conducted for pulsars in the dynamically complex central region of the Milky Way. The study, led by […]

Experiment relies on pulsars to probe dark matter waves

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. While some past studies gathered indirect hints of its existence, dark matter has never been […]
