Latest observations, tips, and discoveries from the cosmos
Astronomers have found the first atmosphere on a rocky planet in a star's habitable zone. LHS 1140 b, 48 light-years away, is leaking helium into space.
India's first privately built rocket has reached orbit. Skyroot's Vikram-1 launched from Sriharikota on 18 July carrying six payloads.
SpaceX's Starship Flight 13 aborted at zero seconds on 16 July after four engines failed to light. Here's what went wrong and when it flies again.
A new planet has been discovered by NASA's James Webb telescope. Beta Pictoris d was found not by its light, but by the chemical fingerprint of its atmosphere.
Declassified file DOE-UAP-D002 shows Manhattan Project physicist James Tuck quietly investigating the Los Alamos green fireballs. Here's what it says.
The Senate Intelligence Committee has subpoenaed defence contractors over legacy UAP programmes. Here's what's known, and why the November deadline matters.
The solar eclipse on 12 August 2026 is the deepest seen from the UK since 1999, with up to 96% of the Sun covered. Times, safety and what to expect.
Reflect Orbital has FCC approval to launch its first space mirror and beam sunlight to Earth at night. Astronomers fear 50,000 could follow.
China has landed an orbital rocket booster for the first time. The Long March 10B was caught by a net on a ship at sea, a world-first technique.
NASA has UFO images it can't explain, administrator Jared Isaacman has confirmed. What he actually said, and why his Mars comment might be the bigger story.
The Pentagon's fourth UFO file release covers a nuclear site lockdown, the 1949 green fireballs and new footage from near China. Here's what's really in it.
NASA's TESS has discovered a new planet by bending spacetime: Gaia23bra b, a super-Jupiter 40,000 light-years away, found via gravitational microlensing.
How big is the Milky Way? NASA's Chandra has found two of our galaxy's spiral arms sit about 10% further out than we thought, measured with X-ray light echoes.
The oldest quasars ever discovered: ESA's Euclid telescope has found 31 from the universe's first 770 million years, including two new record-holders.
Earth reached aphelion on 6 July 2026 — its farthest point from the Sun all year. So why is it the middle of summer? The answer is all about tilt.
A new UFO whistleblower is talking to Congress — behind closed doors first. Why the SCIF-first strategy is a deliberate break from the Grusch playbook.
Avi Loeb is leading the White House's new UFO council, and scientists are pushing back. Here's what the critics say and why it matters.
China's Tianwen-2 spacecraft has arrived at Kamo'oalewa, Earth's quasi-moon that may be a blasted-off chunk of our real Moon. Here's what happens next.
The northern horizon stays live tonight. After the first cloud from the 30 June X1.1 solar flare sparked G1–G2 (Minor to Moderate) storming over the weekend, a second coronal mass ejection is now inbound and forecast to reach Earth late on Sunday 5 July or into Monday 6 July. The Met Office expects Unsettled to Active conditions through the day, then a likelihood of further G1–G2 storming and a chance of isolated G3 (Strong) intervals once that cloud arrives — enough to bring aurora into play for Scotland, Northern Ireland and much of northern England during Sunday night's short window of darkness. The catch is still the calendar: barely two weeks past the solstice, the UK gets almost no true darkness, so timing is everything. Here's exactly when and where to look.
Hayabusa2 flies past asteroid Torifune today at 10:30am UK time, passing just 1km away at 12,000mph. Here's what's happening and how to watch live.
A potentially habitable super-Earth has been found 25 light-years away. New measurements show GJ 3378b is rocky and sits in its star's Goldilocks zone.
The Swift rescue mission was delayed mid-flight on 2 July after a problem stopped the last Pegasus rocket from launching. Here's what happened and what's next.
The Swift rescue mission launches today at 10:09am UK time. The last Pegasus rocket ever will carry a robot to catch NASA's falling telescope. Here's how to follow it.
UFOs over military bases forced F-22s to relocate from Langley, says ex-Pentagon official Christopher Mellon. Hundreds of incursions a year, and no answers.
