How the superfast flight of astronauts and fighter pilots changes their brains
Unlike 'Top Gun', real-life fighter pilots are careful thinkers in the air. Learning how their brains change could assist astronauts with critical mission decisions, a new study says.
What is the Nancy Grace Roman Space Telescope?
The Nancy Grace Roman Space Telescope is the next major step in astronomy and will help unlock the secrets of the universe's expansion and dark energy.
Magnetars are Extreme in Every Way, Even Their Volcanoes
In a recent study published in Nature Astronomy, an international team of researchers led by NASA and The George Washington University examined data from an October 2020 detection of what’s known as a “large spin-down glitch event”, also known as an “anti-glitch”, from a type of neutron star known as a magnetar called SGR 1935+2154 and located approximately 30,000 light-years from Earth, with SGR standing for soft gamma repeaters. Such events occur when the magnetar experiences a sudden decrease in its rotation rate, which in this case was followed by three types of radio bursts known as extragalactic fast radio bursts (FRBs) and then pulsed radio emissions for one month straight after the initial rotation rate decrease.
Elegoo Neptune 3 Plus review: the total package
The Elegoo Neptune 3 Plus ticks all the boxes when it comes to FDM 3D printers.
New satellite photos show surface cracks from devastating Turkey earthquake
Earth-observation satellites continue to assess the vast damage in Turkey and Syria caused by the devastating series of earthquakes that struck on Feb. 6.
Task complete! Perseverance Mars rover snaps photo of filled sample depot
NASA's Perseverance Mars rover recently snapped a photo of the Three Forks sample depot, which contains 10 samples for possible future return to Earth.
Lego Star Wars AT-TE Walker review
The return of the Lego Star Wars AT-TE Walker has been at the top of many a fan's wish list for years, and Lego has delivered the best-looking rendition yet
Mini astrobiology laser could join hunt for life on Mars and beyond
A mass spectrometer called the Orbitrap has been scaled down to fit on astrobiology missions to planets and moons of the solar system.
Chelyabinsk meteor explosion was a planetary defense wakeup call
On Feb. 15, 2003, a meteor exploded over the Russian city of Chelyabinsk, showing why we need better methods of detecting and tracking near-Earth asteroids.
Here's how China's astronauts keep fit aboard Tiangong space station (video)
China's astronauts are working up a sweat in orbit with a variety of exercise machines designed to keep them fit and fight the loss of bone density that comes with living in microgravity.
Chelyabinsk a decade on: the Sun's invisible asteroids
Image:
No one saw the Chelyabinsk meteor of 15 February 2013 coming – the largest asteroid to strike Earth in over a century. Just after sunrise on a sunny winter’s day, a 20-metre, 13 000 tonne asteroid struck the atmosphere over the Ural Mountains in Russia at a speed of more than 18 km/s.
ESA signs Cooperation Agreement with Mexico
ESA and the Mexican space agency, Agencia Espacial Mexicana (AEM) signed a Cooperation Agreement on 14 February 2023. The objective of this agreement is to allow Mexico and ESA to create a framework for more-intensive cooperation in joint projects in the future.
Virgin Orbit traces failed UK rocket launch to 'dislodged fuel filter'
Virgin Orbit's first-ever launch from the United Kingdom was apparently doomed by a fuel filter that got knocked out of place.
Why are Jupiter’s Trojan Regions so Unevenly Balanced With Asteroids?
Solar systems evolve, especially early on in their lifetimes. While this evolution is primarily driven by gravity, there are some parts of our own solar system that are difficult to understand – especially how gravity forced them into their current configuration. One of the most prominent of these areas is the Trojan asteroids.
Mars rover completes first sample storage depot
NASA’s Perseverance took this selfie of itself looking down at one of 10 sample tubes deposited at the sample depot it created in an area nicknamed “Three Forks.” This image was taken by the WATSON camera on the rover’s robotic arm on Jan. 20, 2023, the 684th Martian day, or sol, of the mission.

NASA’s Perseverance rover on Mars has cooly notched up another significant first by creating the first ever storage depot on another world for Martian soil samples. But if the rover’s mission goes to plan and it continues to operate as scheduled, the cached samples could be left on the Martian surface forever.

Big asteroid to zoom by Earth on Wednesday
A sizable asteroid will make its closest approach to Earth in four centuries on Wednesday evening (Feb. 15), but there's nothing to fear.
Another Meteoroid Discovered Right Before it Hits the Atmosphere
A meteoroid lit up the sky above the English Channel early Monday morning February as it streaked through the atmosphere, and because it had been detected just a few hours beforehand – with expert precision on where it could be seen — skywatchers were able to capture the event.
'Starspots' could improve our understanding of habitable zones
A new technique to measure starspots could help test stellar magnetism theories and improve our understanding of habitable zones.
