Saturn Auroras from Hubble.

This could be exciting - a possible optical counterpart to a recently detected black hole-neutron star merger. Worth keeping an eye on...

#OnThisDay in 1993, CERN put the World Wide Web in the public domain, later made available with an open licence, allowing the web to flourish.

Here we see Sir Tim Berners-Lee's proposal for the World Wide Web, revised back in May 1990.

The World Wide Web will be one of the…

Imagine life on a planet that's tidally locked to its star; the day side is smeltingly hot and the night side is in permanent darkness (although winds still carry heat around)

Free tickets for my last Gresham College lecture of the year are up. In London or online.

Why the physics of particles might be on the verge of a revolution, how black holes evaporate, and when relativity inspires young minds. It’s “Phreaky Physics,” on Big Picture Science. Listen here: buff.ly/3UDINz5

A star-gazer’s alert here. It looks like we may be treated to a major supernova viewing at some point this year when the “Blaze Star”, T Coronae Borealis explodes – and from what I’ve read, this may be a once-in-a-lifetime observable phenomenon. There aren’t any specifics on date…

Mars.

Yesterday.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

Here we see one of the ProtoDUNE particle detectors being filled with liquid argon, a process that takes about two months.

The liquid argon’s inert properties facilitate precise measurements, enhancing detection capabilities.

ProtoDUNE is a prototype of the Deep Underground…

This is a very important mission in my opinion - are we alone in the local Universe - good question :-) I’m delighted that NASA are doing what they do best; difficult things that really matter!

A few more from the Texas total eclipse… Next stop Greenland August 2026! #eclipse2024

The one in a trillion coincidence that makes total solar eclipses possible:

the Moon's diameter is 400 times less than the Sun's diameter, yet it is also 400 times nearer to Earth.

“Besides his outstanding contributions to particle physics, Peter was a very special person, an immensely inspiring figure for physicists across the world, a man of rare modesty, a great teacher and someone who explained physics in a very simple and yet profound way. (1/2)

Very sorry to hear Peter Higgs has died. I was fortunate enough to meet him several times, and beyond being a famous physicist - I think to his embarrassment at times - he was always charming and modest. And of course his name will be remembered as long as we do physics in the…

'Absence of evidence is not the evidence of absence'

BREAKING! This image - released just minutes ago - shows our Milky Way galaxy's central, giant black hole in polarized light. It's the 1st-ever image of its kind! Read more about this spectacular image:

#OnThisDay in 1655, Christiaan Huygens FRS discovered Saturn's largest moon Titan. In the 20th century, Titan was discovered to have a thick atmosphere of with an abundance of methane, the only natural satellite in the solar system to do so. #Astronomy bit.ly/2USdJKI

ESA study selects Enceladus as target for mission in the 2040s. So excited there are finally the beginnings of a plan to get back to this fascinating tiny world.

16mm film camera footage showing the descent and landing of the Apollo 11 LM Eagle on July 20, 1969. You can see the boulder field that Neil Armstrong had to avoid by continuing further west, passing over Little West crater and touching down about 60 meters beyond.
