The European Space Agency has announced a timeline for key testing milestones for its upcoming next-generation Ariane 6 rocket.
A star is born! How cosmic winds are a key step in stellar formation
Astronomers have determined that cosmic winds around clouds of gas and dust are key for the formation of hot and dense young stars.
Striking New Views of Jupiter and Its Moon Io
The James Webb Space Telescope and Juno mission turned their eyes to Jupiter and its volcanic moon Io, revealing fine details.
How astronaut Thomas Pesquet captured the planet in 'The Earth in Our Hands'
Flipping through his new book of more than 200 photos of Earth taken during his second stay on the International Space Station, you get the sense Thomas Pesquet thoroughly captured the planet.
How Close is Too Close to a Kilonova?
Cataclysmic events happen in the Universe all the time. Black hole mergers, supernovae, gamma-ray bursts, and a whole host of others. Most of them happen in distant galaxies, so they pose no threat to us. But there are a few that could affect life on Earth, and a couple could even pose an existential threat. One of these threats is known as a kilonova.
A Kilonova Simulated in 3D
In 2017, astronomers detected gravitational waves from colliding neutron stars for the first time: a kilonova. Enormous amounts of heavy metals were detected in the light from the explosion, and astronomers continued to watch the expanding debris cloud.
Gulf Stream weakening now 99% certain, and ramifications will be global
A new analysis has concluded that the Gulf Stream is definitely slowing, but whether it's due to climate change is hard to tell.
Nearby asteroid may contain elements 'beyond the periodic table', new study suggests
Naturally occurring superheavy elements beyond those listed in the periodic table could potentially explain why asteroid 33 Polyhymnia is so dense, new research suggests.
Don't miss a partial lunar eclipse of October's Full Hunter's Moon this week
October 2023's Full Hunter's Moon will see the lunar disk slip into the shadow of Earth for a partial lunar eclipse on Saturday, Oct. 28
What is an attosecond? A physical chemist explains the tiny time scale behind Nobel Prize-winning research
A group of three researchers earned the 2023 Nobel Prize in physics for work that has revolutionized how scientists study the electron – by illuminating molecules with attosecond-long flashes of light.
The moon may be 40 million years older than we thought, Apollo 17 samples suggest
A new analysis of moon samples brought to Earth in 1972 reveals the moon is 4.46 billion years old.
'Sew Sister' Jean Wright shares her NASA space shuttle experience with new book
Jean Wright used to sew critical hardware for NASA's space shuttle program. A new book by Elise Matich celebrates the "Sew Sister" team that brought astronauts into space.
Strange anomaly in sun's solar cycle discovered in centuries-old texts from Korea
Aurora records in royal chronicles from Korea show that during the 'Maunder Minimum' between 1645 and 1715, the sun's solar cycles became several years shorter than they are today.
An Unusual Crater on Pluto Might be a Supervolcano
Pluto with a super-cryovolcano? Why not! All the elements are there, just not in the way we normally think of volcanoes. And, cryovolcanoes are the reason why Pluto’s surface looks the way it does. A recent research paper explains why Pluto could be the home of the latest supervolcano discovery in the Solar System.
JWST Looks at the Debris Disc Around a White Dwarf
Debris disks are quite common in the Universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around neutron stars. So what about white dwarfs?
Space Perspective unveils 'Space Spa' restroom for balloon tourist flights (images)
Space Perspective introduced its latest addition to its space tourism operation: a uniquely designed restroom called the 'Space Spa' that will be a key part of its Spaceship Neptune capsule.
China is building the world's largest underwater telescope to hunt for elusive 'ghost particles'
China's forthcoming Tropical Deep-sea Neutrino Telescope (TRIDENT) will search for the origins of cosmic rays in momentary flashes of light beneath the ocean's surface.
Now Astronomers have Discovered “Ultra-Fast Radio Bursts” Lasting Millionths of a Second
A recent study published in Nature Astronomy examines the discovery of what astronomers are dubbing “ultra-fast radio bursts”, a new type of fast radio bursts (FRBs) that the team determined lasts for a mind-boggling ten millionths of a second or less. Traditionally, FRBs have been found to last only thousandths of a second, but this study builds on a 2021 study that hypothesized FRBs could possibly last for millionths of a second. This also comes after astronomers recently announced the discovery of the oldest and farthest FRB ever observed, approximately 8 billion light-years from Earth.
NASA Tests a 3D Printed Aluminum Rocket Nozzle
When it comes to the current era of space exploration, one of the most important trends is the way new technologies and processes are lowering the cost of sending crews and payloads to space. Beyond the commercial space sector and the development of retrievable and reusable rockets, space agencies are also finding new ways to make space more accessible and affordable. This includes NASA, which recently built and tested an aluminum rocket engine nozzle manufactured using their new Reactive Additive Manufacturing for the Fourth Industrial Revolution (RAMFIRE) process.
A Russian Satellite Has Shifted Within 60 km of Another Spacecraft
When it comes to saber-rattling, few countries employ it as much as Russia does. During their ongoing invasion and occupation of Ukraine, the country’s leadership has repeatedly threatened to use atomic weapons. But the threats don’t stop there.
