Our Sun is capable of terrifying outbursts – and now scientists have discovered evidence of its biggest tantrum on record. Tree rings dating back 14,000 years contain a radiocarbon spike twice as powerful as the previous biggest known solar storm.

Lifestyle interventions to treat or prevent type 2 diabetes and obesity are not the easiest changes. Now, a study suggests that a prescribed period of natural light during the day could significantly improve health markers, with little effort required.

India is furthering its bid to become a major spacefaring power. The launch of its first mission to the Sun comes just as it winds down its first successful robotic Moon landing, with the Pragyan lunar rover completing its work and going into sleep mode.
-
Solar wind – charged particles from the Sun – pervades our solar system, but the exact mechanism behind it remains murky. Now ESA’s Solar Orbiter spacecraft has observed previously unknown tiny flares on the Sun’s surface spewing plasma into space.
-
Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt, at least five times more energetic than previously known.
-
In a scary first, scientists have discovered a 2021 solar eruption so large that it was, for the first time, detected simultaneously on Earth, the Moon, and Mars, highlighting the radiation dangers posed by such events to deep space travelers.

If you’ve ever felt like you need more hours in the day, well how does 60 sound? A new study suggests we’d have 60-hour days by now if a stalemate between the Sun and Moon hadn’t interfered with Earth’s rotation for over a billion years.
-
Radioactive isotopes found in meteorites suggest a supernova went off right near the Sun as it was forming – but that should have blasted the young solar system away. So how did we survive? A new study proposes an explanation.

The annual Astronomy Photographer of the Year competition highlights the beauty of the night sky. The shortlist for 2023 has now been published, starring some stunning shots of the Sun, our majestic Milky Way, and awe-inspiring aurorae.
-
This space oddity has long puzzled scientists for its peculiar non-asteroid-like behaviors. Researchers have now uncovered another curious characteristic of 3200 Phaethon, this time with its dazzling tail, rewriting 14 years of science knowledge.
-
Dark matter remains elusive despite decades of searching. Now physicists have proposed a new experiment that would try to find signals by sending atomic clocks to where dark matter should be at its most dense – right near the Sun.
-
Astronomers have discovered three new near-Earth asteroids, including the closest known to the Sun. Another is one of the largest known asteroids considered potentially hazardous to Earth, measuring almost a mile wide with an orbit close to our own.
