'True embarrassment' of astronomy resolved as missing matter is found

After an intergalactic search lasting more than two decades, an Australian-led team of scientists say they have finally found the universe's "missing matter", solving a mystery that has long stumped astronomers.

I thought I found the missing 2.5% of baryonic matter around my waste. The conversation has an article by the researchers - https://theconversation.com/half-th...ssing-we-found-it-hiding-in-the-cosmos-138569 It's a good example of how important better 'eyes' are for pushing science and improving our understanding of reality, just as the microscope and telescope did centuries earlier.

Who's gunna watch the SpaceX launch? It's due for 6:33 am eastern Aus time. I gather there's quite a few live streams.
EDIT: It's been scrubbed for today

Did you watch it today? Weather was good and the launch went perfectly.

The live feed from NASA was a bit Murica * Yeah. You would have thought this was the first rocket ever to go to the ISS. No mention of the Russians taking 100 people up and down over the last nine years. No mention of the three guys currently on the ISS.

The live feed of the booster landing back on the drone ship cut out, then when it came back up the rocket was sitting there. Looked fake lol.

Haha was sooo fake- I farkin' lol'd when that happened. Anyone believing it landed perfectly deserves to have that rocket rammed up their arse

Nah, I missed it. Spewin

Apparently the reason behind that is when the rocket gets close it rocks the droneship bad enough the camera signal that gets beamed up to a satellite ends up missing the satellite causing it to cut out. Once it's landed and the droneship settles the signal restores.

Yeah I saw that explanation. If that is correct it's been a known issue for a few years which could have easily been addressed. Such as having a local link to a nearby support ship that maintains the signal to the satellite. A helicopter or flying drone could have captured the landing. If it's an issue with the uplink then a recording of the video from the drone ship should have been made available by now. What happened to the video from the booster rocket that we were viewing live as it descended - until a few seconds before it was due to land?

It seems strange that every other aspect of the mission was covered by live hi-def video yet from the drone landing ship we get a murky low-res picture that cut out at the vital moment.

There is a reason that the landing ship is not manned.

Scientists say most likely number of contactable alien civilisations is 36

New calculations come up with estimate for worlds capable of communicating with others

Too bad it wasnt 42

I am going to buy my first Telescope. Any recommendations? I would like something powerful enough to catch a glimpse of the Andromeda Galaxy.

I sure hope it's a real planet and not a miniature black hole FFS!!!

Astronomers want to figure out What the hell Planet Nine is once and for all

"One of the ideas put forth was the possibility that Planet Nine could be a grapefruit-sized black hole with a mass of five to 10 times that of the Earth."

That whole Betelgeuse dimming thing was just an eruption that lead to dust blocking part of the star. I'd love to see a supernova but I'm sort of glad that we can put that theory to bed for the moment. Give me Eta Carinae exploding over Betelgeuse; prime viewing down here in the southern hemisphere

Why astrophysicists think there's a black hole in our solar system

Unusual gravitational activity has been found in the outer solar system. It could be a ninth planet but scientists now propose it's a black hole.

Got you all covered for the super conjunction tonight.

No need to look up.

Must send Brad Pitt to investigate.

The Perseverance Rover is due to land on Mars tomorrow morning (approx 7:45am AEDT), and you can watch it in real time if you want

NASA's Perseverance rover gears up to land on Mars in 'seven minutes of terror'

After a seven-month journey, the Perseverance rover will attempt to land on the Red Planet tomorrow morning (AEDT). And even though NASA has done this before, it won't be easy. Here's what's involved.

Wow, that was tense!

First colour pictures of "Percy" have been released






A HD video with sound of the whole landing is expected sometime next week

They should have joined Prime.

Incredible stuff.
Surely they'll find evidence of a bacteria from 40,000 years ago or the like.
They need to send another vessel to pick up the samples as well.

We have an Australian led and designed mission on Percy. It has not got the media attention it deserves. Dr Abigail Allwood, is a geologist, is one of seven principal investigators chosen for the mission. Read about it here - NASA's latest Mars mission with Perseverance has two very interested Australians: Abigail Allwood and David Flannery - ABC News It's a great achievement and should be celebrated more widely. I struck by this sentence, showing the order of magnitude change that happens when you get into the big league.

"With $US 1.3 billion in funding, work began to develop a full-scale version of the PIXL prototype."

I'm not sure she would have ever dreamed of getting $10 million to develop the instrument, much less over a billion.

Is the Sun exactly the same strength in Australia 3 months before the solstice as it is 3 months after?
