Houston, you've got visitors
Last week, members of ESA’s astronaut class of 2022 embarked on their first overseas field trip. They visited NASA’s facilities at the Johnson Space Centre (JSC) in Houston, Texas, USA, to get familiar with the environment where they will spend a significant part of their training once assigned to a mission.

Top 10 Earth observation stories of 2023
This year has been a whirlwind of captivating Earth observation stories and news, spanning from dramatic volcanic eruptions to powerful earthquakes to witnessing icebergs on the run. Join us as we revisit some of the most memorable stories from 2023.
Strange 'slide whistle' fast radio burst picked up by alien-hunting telescope defies explanation
The fascinating patterns of 35 repeating fast radio bursts (FRBs) reveal new properties of these mysterious blasts of deep-space radiation that appear and disappear in milliseconds.
Blue Origin’s New Shepard Completes 24th Flight; New Glenn Hopefully on the Horizon
Blue Origin’s New Shepard rocket successfully launched and landed today at the company’s Launch Site One in West Texas, with an uncrewed science and goodwill payload onboard. This was the 24th New Shepard flight and 13th payload mission today from Launch Site One in West Texas.
Can Webb Find the First Stars in the Universe?
The Universe’s very first stars had an important job. They formed from the primordial elements created by the Big Bang, so they contained no metals. It was up to them to synthesize the first metals and spread them out into the nearby Universe.
Watch Chinese astronauts get haircuts aboard Tiangong space station (video)
Shenzhou 17 commander Tang Hongbo and rookie crewmates Tang Shengjie and Jiang Xinlin recently helped each other get haircuts aboard China's Tiangong space station.
Astronomers Find Two Planetary Systems Around Sun-Like Stars
NASA’s Transiting Exoplanet Survey Satellite (TESS) has been busy. Clocking in over 5000 exoplanet candidates, the researchers who manage the telescope’s data have enlisted an army of volunteer classifiers to sift through its data to confirm whether these planets exist. In a new paper in Astronomy & Astrophysics, some researchers from Brazil think they have found three planets that almost certainly do – and they happen to orbit stars that are very similar to our own Sun.
Astronomers Find 100,000-light-year Bow Shock in the Milky Way’s Outskirts
New simulations showed astronomers where to look for evidence of a dwarf galaxy's bow shock as it crashes through the Milky Way's halo.
How the runaway greenhouse gas effect can destroy a planet's habitability — including Earth's
Scientists watched as a simulated planet was driven from a habitable Earth-like heaven to an inhospitable Venus-like hell as the result of a runaway greenhouse effect, delivering a stark climate message.
A Radio Telescope on the Moon Could Help Us Understand the First 50 Million Years of the Universe
In the coming decade, multiple space agencies and commercial space providers are determined to return astronauts to the Moon and build the necessary infrastructure for long-duration stays there. This includes the Lunar Gateway and the Artemis Base Camp, a collaborative effort led by NASA with support from the ESA, CSA, and JAXA, and the Russo-Chinese International Lunar Research Station (ILRS). In addition, several agencies are exploring the possibility of building a radio observatory on the far side of the Moon, where it could operate entirely free of radio interference.
NASA laser-beams adorable cat video to Earth from 19 million miles away (video)
NASA's Deep Space Optical Communications experiment streamed a high-definition video of Taters the cat to Earth from 19 miles (31 million km) away in a groundbreaking demonstration.
Blue Origin launches New Shepard rocket on return to flight mission
A Blue Origin New Shepard rocket lifts off from the launch site in Van Horn, Texas, on the NS-24 mission. This was the first launch of a New Shepard rocket since the vehicle was grounded in the after math of the NS-23 anomaly. Image: Blue Origin

Why String Theory Requires Extra Dimensions
String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force carriers called gluons, would supplant it, but in the deep mathematical bones of the young string theory physicists would find curious structures, half-glimpsed ghosts, that would point to something more. Something deeper.
Pew! Pew! Pew! NASA's 1st successful two-way laser experiment is a giant leap for moon and Mars communications
NASA has completed its first laser link with an in-orbit laser relay system, marking a significant advancement in space communication technology.
Hubble Telescope captures a galaxy's 'forbidden' light in stunning new image
The "forbidden" light of the spiral galaxy MCG-01-24-014 is captured in a new image from the Hubble Space Telescope, suggesting the galaxy contradicts common rules of quantum physics.
Everything we know about 'Alien: Romulus'
Xenomorphs are invading the big screen once again with a movie from 'Evil Dead' helmer Fede Álvarez. Here's what we know about 'Alien: Romulus' so far.
James Webb Space Telescope may have found the oldest black hole in the universe
The James Webb Space Telescope's discovery of the universe's oldest black holes is giving astronomers some vital clues for how they came to be.
This alien planetary system has a Jupiter world 99 times wider than Earth
Astronomers found two planetary systems centered around solar analogs containing mini-Neptune planets and a "super-Jupiter" world 99 times the size of Earth.
