"The James Webb Space Telescope has opened a new frontier in extragalactic astrophysics, revealing objects we didn't even suspect existed, and we're only at the beginning of this adventure."
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).
The brief flashes were captured from Earth and could be from the Taurid meteor shower.

The Copernicus Sentinel-1D satellite has joined the Sentinel-1 mission in orbit. Launch took place on 4 November 2025 at 22:03 CET (18:03 local time) on board an Ariane 6 rocket from Europe’s Spaceport in French Guiana.
"This discovery ends a protracted search for these waves that has its origins in the 1940s."
China's Shenzhou 20 and 21 astronauts enjoyed freshly cooked BBQ aboard the Tiangong space station recently, thanks to a new microgravity oven.
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.
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 tells a surprisingly human story of self-acceptance through the lens of sci-fi's most brutal hunter.
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?
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.
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.
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).
The European Space Agency and NASA's Hubble Space Telescope recently visited the spiral galaxy NGC 3370
Astronomers have found that star-forming galaxies in the early universe were far messier than modern-day disk galaxies.
The Jovian moons Io and Europa will throw their shadows over Jupiter's cloud surface in the early hours of Nov. 5.
Europe's Ariane 6 heavy-lift rocket successfully launched the Sentinel-1D Earth-observing satellite today (Nov. 4) on its fourth-ever launch.
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.
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.
