NASA's NICER finds X-ray boosts in the Crab Pulsar's radio bursts
A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected.

More than 5,000 tons of extraterrestrial dust fall to Earth each year
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program conducted for nearly 20 has determined that 5,200 tons per year of these micrometeorites reach the ground.

Mars didn't dry up in one go
A research team has discovered that the Martian climate alternated between dry and wetter periods, before drying up completely about 3 billion years ago.

Corals carefully organize proteins to form rock-hard skeletons
Scientists have shown that coral structures consist of a biomineral containing a highly organized organic mix of proteins that resembles what is in our bones. Their study shows that several proteins are organized spatially -- a process that's critical to forming a rock-hard coral skeleton.

Evidence of Antarctic glacier's tipping point confirmed
Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.

A new state of light
A single 'super photon' made up of many thousands of individual light particles: About ten years ago, researchers produced such an extreme aggregate state for the first time. Researchers report a new, previously unknown phase transition in the optical Bose-Einstein condensate. This is a overdamped phase.

Astronauts Will Soon be Getting a Space Fridge, Keeping Everything Cold in Zero-G
One of the least known of NASA’s funding mechanisms is the Small Business Innovation Research (SBIR) program. This program, required by the Baye-Doyle Act of 1980, earmarks a piece of every US Federal agency’s budget (including NASA) for the development of small businesses to commercialize new technologies. NASA’s SBIR program usually focus on commercializing technologies …

Biden Administration is Looking for a 6.3% Increase in NASA’s Budget for 2022
Space research, like much else in capitalist societies, is driven by funding. The biggest source of that funding for that space research is usually the US government. Which is why, when US presidents release their budget proposals, the space community takes notice. Especially because that budget affects NASA, the largest space funding agency in the …

Ground-Based Lasers Could Push Space Debris off Collision-Course Orbits
Researchers at the Australian National University (ANU) are finding new uses for the laser-based technology that sharpens telescope imagery – called adaptive optics – and it just might help mitigate the world’s growing space debris problem. Purpose-built lasers could give derelict satellites a slight ‘push’ of photons, imparting just enough energy to change the debris’s …

100-meter Asteroid Created a Strange Impact Event in Antarctica 430,000 Years Ago
The effects of ancient asteroid impacts on Earth are still evident from the variety of impact craters across our planet. And from the Chelyabinsk event back in 2013, where an asteroid exploded in the air above a Russian town, we know how devastating an “airburst” event can be. Now, researchers in Antarctica have discovered evidence …

Earth Gains 5,200 Tons of Dust From Space Every Year
Whenever I wipe the dust off my coffee table or catch a glimpse of dust motes floating in sunlight, my spacey mind always wonders, is any of that cosmic dust? It just might be. But the amount of space dust that lands on our planet every year might surprise you. Scientists have long known that …

Astronaut selection: tips from Thomas
Video:
00:02:18
In 2008, Thomas Pesquet applied to become an ESA astronaut. On 22 April 2021, he will fly his second mission to the International Space Station. In this video Thomas shares how he found his way to space, and encourages viewers to follow their passions as ESA seeks its next class of astronauts.
Nobody is perfect on their first attempt at a task, but Thomas says the only way to improve is to try and keep trying. Though becoming an astronaut seemed a distant dream when he was younger, by continuing to challenge himself and learn along the way he developed the skills he needed to put himself forward and become one of a small group who have travelled to space.
Whatever your passion, his advice is universal: try your best...

Space Debris
Video:
00:04:15
On 20 April 2021, ESA will host the 8th European Conference on Space Debris from Darmstadt, in Germany. Scientists, engineers, industry experts and policy makers will spend the virtual four day conference discussing the latest issues surrounding space debris. They will exchange the latest research, try to come up with solutions for potential problems and define the future direction of any necessary action.
There are currently over 129 million objects larger than a millimetre in orbits around Earth. These range from inactive satellites to flakes of paint. But no matter how small the item of debris, anything travelling up to 56 000 km/h in an orbit is dangerous if it comes into contact with the many satellites that c...
