The 1st light to flood the universe can help unravel the history of the cosmos. Here's how
Just as Darwin used the fossil record to piece together the evolution of life on Earth, scientists can use a "cosmic fossil," the universe's first light, to understand how the cosmos evolved.
Unintended Satellite Emission May Harm Radio Astronomy
Satellites’ leakage radiation, now detected for the first time, may become a major problem for radio astronomy, as “megaconstellations” keep on growing.
A Neutron Star is Unwinding a Companion Star
Close binary stars play several important roles in astronomy. For example, Type Ia supernovae, used to measure galactic distances, occur when a neutron star in a binary system reaches critical mass. These stars are also the source of x-ray binaries and microquasars, which help astronomers understand supermassive black holes and active galactic nuclei. But the evolutionary process of close binaries is still not entirely understood. That’s changing thanks in part to a new discovery of a close binary in its intermediate stage.

Chandrayaan-3: A guide to India's third mission to the moon
Chandrayaan-3 is the third Indian mission to the moon. It aims to deploy a lander and a rover to the lunar surface for 14 Earth days to gather science and imagery.
Boom! Watch an inflatable space habitat explode during testing (video)
Lockheed Martin recently completed a successful burst test of the company's sub-scale inflatable space habitat, pushing past safety limits to explode the module at the company's Colorado facility.
Guiding Aeolus' safe reentry
After exceeding its planned life in orbit, ESA’s Aeolus wind satellite is on its way back to Earth. The satellite is currently falling around 1 km a day, and its descent is accelerating. ESA’s spacecraft operators will soon intervene and attempt to guide Aeolus in a first-of-its-kind assisted reentry. Why is ESA doing this?
James Webb Space Telescope spots violent collision between neutron stars
The James Webb Space Telescope traced the second-brightest gamma-ray burst ever seen to a kilonova, a collision between two neutron stars — an event believed to forge heavy elements like gold.
Train me to the Moon and back
Two European astronauts are following the traces of a treasure trove of rare, Moon-like crystals in a Norwegian fjord as part of the PANGAEA geology training course.
Space for travellers
As the 2023 summer holiday season gets under way, ESA and Amsterdam’s international airport are once again giving travellers a chance to discover some out-of-this-world destinations.
See the Red Planet Mars shine beside the blue star Regulus tonight
Look to the western skies on Monday evening (July 10) to see the Red Planet, Mars, shining steadily above the twinkling blueish star Regulus.
Is the puzzling star Betelgeuse going to explode in our lifetime after all?
A new unpublished study is making waves on the internet, claiming that one of the brightest stars in the night sky might die in a spectacular explosion within our lifetime.
Help ESA research key space-based solar power challenges
Space-based solar power could provide Earth with clean and reliable energy, 24 hours a day. As part of its SOLARIS initiative, ESA is inviting researchers to help advance our knowledge of key aspects of collecting solar power in space and wirelessly transmitting it to Earth.
Cheops shows scorching exoplanet acts like a mirror
Data from ESA’s exoplanet mission Cheops has led to the surprising revelation that an ultra-hot exoplanet that orbits its host star in less than a day is covered by reflective clouds of metal, making it the shiniest exoplanet ever found.

Save over 50% on Celestron Outland X 10x42 binoculars — ideal for all-weather camping trips, sporting events, festivals and occasional skywatching.
A Planet has Whipped Up Spiral Arms Around a Young Star
When you hear the phrase “spiral arms” you probably think of galaxies. Lots of galaxies have bright arcs of stars that spiral away from their center, including our Milky Way. But not all galaxies have spiral arms, and galaxies aren’t the only celestial objects with spiral arms. About a third of protoplanetary disks around young stars have spiral arms, and we now think we know why.
The climate of Mars changed dramatically 400,000 years ago, Chinese rover finds
A shift in Mars' climate 400,000 years ago produced a change in wind direction that left its mark in the erosion of bright sand dunes.
Mushroom-shaped superplume of scorching hot rock may be splitting Africa in 2
Strange, never-before-seen movements in the East Africa Rift Valley appear to be driven by super-heated rock from deep beneath Earth's surface.
James Webb telescope detects the earliest strand in the 'cosmic web' ever seen
Astronomers using the James Webb Space Telescope have discovered a clump of ancient galaxies that may be the oldest strand of the "cosmic web" ever detected.
