Asteroid Bennu: complex origins, dramatic transformations A trio of papers published in Nature Astronomy and Nature Geoscience unfolds the long history enclosed in tiny Bennu samples. Read more: go.nasa.gov/4mp1SAd

@sainsburys It was in the Altrincham store, between about 10:30 and 11:00 this morning (at whatever time it was when they tested their fire alarms!)

@SarahACrowther Hi Sarah. Sorry the fire exit was blocked! Which store was this? I'll get that fed back. Emma

@sainsburys informing customers that the fire alarms in store are being tested is great. Perhaps access to fire exits should be checked at the same time... They should never be blocked with stock waiting to be unloaded onto shelves.

What's wrong here @marksandspencer?

So this has been annoying me all series - why do they never put up the hoods of their Tyvex bunny suits in Silent Witness?

Not only does Bennu contain all 5 of the nucleobases that form DNA and RNA on Earth and 14 of the 20 amino acids found in known proteins, the asteroid’s amino acids hold a surprise go.nature.com/4hAISfn

Rocks and dust from asteroid Bennu contain some of the molecular building blocks of life on Earth: amino acids and nucleobases. They also carry ammonia that formed billions of years ago in cold, distant regions of our Solar System. @MeteorDannyG et al.: nature.com/articles/s4155…

Remember when we brought pristine asteroid samples back to Earth? The first big science is in! The samples suggest that the early solar system had widespread conditions and ingredients for life. Here's how we know: go.nasa.gov/4jxFNP5

In 2023, we brought a sample of an asteroid called Bennu to Earth, part of a plan to study remnants of our early solar system. These grains of rock have shown that the building blocks of life and the conditions for making them existed on Bennu's parent body 4.5 billion years ago.

I allowed extra time than usual to get to an appointment but missed it. Ironically digital display on bus kept highlighting that reliability is one of the 6 commitments of the @BeeNetwork 🤣 Are you going to refund the money I'd paid in advance for the missed appointment?

Left home just before 07:00. Got to Alty station 07:06. After about half an hour waiting in freezing cold, told no trams running. Got 263 bus at 07:44 (late!). Got off bus at RNCM at 09:33. Not happy. @BeeNetwork @AndyBurnhamGM

Apparently there's a connection between eating more chocolate and winning the Nobel Prize. So I'm a little surprised the committee haven't been in touch about my prize yet 🤣 Guess I'll keep trying...🍫 facebook.com/10002720825627…

I think that's me! Not a bad crowd for 3 talks in a row about noble gases, I didn't scare them all of with xenon isotopes 🤣

Space nails! 🚀 🪐

@RobertMMassey @GeorginaRannard @BBCScienceNews @BBCNews Ah good, glad it's been corrected 👍

@SarahACrowther @GeorginaRannard @BBCScienceNews @BBCNews That's a bit embarrassing. Fortunately it's been fixed now.

Mare Tranquillitatis was NOT "probably once an ocean" The name Mare comes from when early astronomers mistakenly thought there were seas on the Moon, but we've known for a long time that they're lava-filled basins bbc.co.uk/news/articles/… @GeorginaRannard @BBCScienceNews @BBCNews

Apparently 7th July is world chocolate day. Just wanted to share that in case anyone needs an excuse... 🍫🍫🍫 #WorldChocolateDay
