Exoplanet scientists are eagerly awaiting the discovery of an atmosphere around a terrestrial exoplanet. Not a thin, tenuous, barely perceptible collection of molecules, but a thick, robust, potentially life-supporting atmosphere. Due to the way we detect exoplanets, most of the terrestrial planets we find are orbiting red dwarfs (M dwarfs).

China's Shenzhou 20 and 21 astronauts enjoyed freshly cooked BBQ aboard the Tiangong space station recently, thanks to a new microgravity oven.
Sputnik
Sputnik 1, the first artificial Earth satellite, was launched by the Soviet Union on October 4, 195This pivotal event marked the beginning of the Space Age and ignited the Space Race between the Soviet Union and the United States. Its successful launch stunned the world and had a profound impact on science, technology, and global politics.
Dark matter obeys gravity after all — could that rule out a 5th fundamental force in the universe?
Scientists have set about discovering if dark matter behaves like ordinary matter in the cosmos, with the answer revealing more about this mysterious "stuff" and casting doubt on the existence of a fifth fundamental force of nature.
'Predator: Badlands' is a human story without a human in sight
Predator: Badlands tells a surprisingly human story of self-acceptance through the lens of sci-fi's most brutal hunter.
The Early Universe Helps Black Holes Grow Big, But Not In The Long Run
At the heart of the Milky Way, just 27,000 light-years from Earth, there is a supermassive black hole with a mass of more than 4 million Suns. Nearly all galaxies contain a supermassive black hole, and many of them are much more massive. The black hole in the elliptical galaxy M87 has a mass of 6.5 billion Suns. The largest black holes are more than 40 billion solar masses. We know these monsters lurk in the cosmos, but how did they form?
These 5 Venus missions could launch in the next decade to study Earth's 'evil twin'
Several new missions to Venus are expected in the late 2020s and early 2030s, but some of them depend on funding that may not materialize.
The hunt for dark matter: a trivia quiz
This quiz dives into the mysterious world of dark matter — what we know, what we don't, and how scientists are chasing shadows across the cosmos.
ESA and AfSA join forces for systems engineering training
From 7 to 10 October 2025, Europe and Africa took another important step toward deepening their cooperation in space. At the ESA Education Training and Learning Facility in ESEC-Galaxia, Belgium, young engineers from across both continents came together for the Space Systems Engineering Training Course, jointly supported by the European Space Agency (ESA) and the African Space Agency (AfSA).

Early Galaxies Were Messy, New Study Finds
Astronomers have found that star-forming galaxies in the early universe were far messier than modern-day disk galaxies.

Europe's powerful Ariane 6 rocket launches Sentinel-1D Earth-observation satellite to orbit (video)
Europe's Ariane 6 heavy-lift rocket successfully launched the Sentinel-1D Earth-observing satellite today (Nov. 4) on its fourth-ever launch.
Taking The Moon's Temperature With Beeswax
Sometimes space exploration doesn’t go as planned. But even in failure, engineers can learn, adapt, and try again. One of the best ways to do that is to share the learning, and allow others to reproduce the work that might not have succeeded, allowing them to try again. A group from MIT’s Space Enabled Research Group, part of its Media Lab, recently released a paper in Space Science Reviews that describes the design and testing results of a pair of passive sensors sent to the Moon on the ill-fated Rashid-1 rover.
Scientists detect biggest black hole flare ever seen — with the power of 10 trillion suns
Astronomers have detected the most distant and biggest black hole flare ever seen, the result of a black hole ripping apart and devouring a star 30 times as massive as the sun.
Trying To Find Baby Planets Swaddled In Dust
When it comes to finding baby, still-forming planets around young stars, the Atacama Large Millimeter/submillimeter Array (ALMA) observatory is astronomers' most adept tool. ALMA has delivered many images of the protoplanetary disks around young stars, with gaps and rings carved in them by young planets. In new research, a team of researchers used ALMA to image 16 disks around young class 0/1 protostars and found that planets may start forming sooner than previously thought.
A Red Dwarf Star with a Brown Dwarf Companion is Changing our Perception of How Stars and Planets Form
Brown dwarfs are a growing area of focus for astronomers, thanks to improved instruments that have the necessary resolution to visualize them. The term describes substellar objects that are about 13 to 80 Jupiter masses, making them too small to become stars, but massive enough to experience some nuclear fusion in their cores and produce heat. Initially theorized in the 1960s, it was not until the mid-1990s that this class of stellar object was confirmed through direct observation. And thanks to next-generation telescopes and improved data-sharing techniques, there are growing opportunities to study these objects.
