More than one asteroid could have spelled doom for the dinosaurs

Quote:
Scientists have found evidence of an asteroid impact crater beneath the North Atlantic Ocean that could force researchers to rethink how the dinosaurs reached the end of their reign.

The team believes the crater was caused by an asteroid colliding with Earth around 66 million years ago – around the same time that the Chicxulub asteroid hit Earth off the coast of today's Yucatan, Mexico, and wiped out the dinosaurs.

Spanning more than 5 miles in diameter, the crater was discovered using seismic measurements, which allow scientists to probe what lies deep below Earth's surface.

Has the Webb Telescope disproved the Big Bang theory?

WEBB TELESCOPE SHATTERS DISTANCE RECORDS, CHALLENGES ASTRONOMERS

Distant galaxies in Webb images suggest we need to rethink star and galaxy evolution in the early universe.

Quote:
Based on the published literature, right now the Big Bang makes 16 wrong predictions and only one right one — the abundance of deuterium, an isotope of hydrogen.

TLDR?
I hate when they confuse sharing scientific discovery with writing a biography for the scientist related.
I don't really care about the scientist. Give me the DATA!

She realised that using weak acid might dissolve bone and reveal any underlaying tissue - found a weird bit of gunk in a petrie dish after three days, and when she looked under a scope found red circles - another lab assistant was a bird specialist and recognised structures in the bone that matched what female birds do in transferring calcium during breeding season to allow egg creation. Long and short was that the T-Rex was a lady dino and about to lay eggs.

Later on after dissolving the bone, she managed to use Ostrich and Emu protein connectors and found dino proteins in the tissue, which have a much better chance of providing DNA strands.

No word yet on life finding a way.

The natural world in your pocket: How citizen science is democratising discovery

Quote:
“It’s a global revolution in biology around the world,” says Jon Sullivan, a senior lecturer in ecology at Lincoln University and one of the team who operates the Aotearoa “node” of iNaturalist, a global platform. The data from my observations as well as thousands of others can be used by scientists here, be fed into international biodiversity databases, and – if the discovery is, say, a new weed – reported to the Ministry for Primary Industries.

iNaturalist is just one of many citizen science projects that use the internet – others spot seals from space, find galaxies in the dark beyond or note kererū numbers across Aotearoa. These online projects, often enabled by omnipresent technology, widen the definition of science and open it up to more people.

RIP India's Mars Orbiter.

After an amazing run at Mars, India says its orbiter has no more fuel

Quote:
India proved that a durable, capable Mars spacecraft could be developed on a shoestring budget. Instead of costing hundreds of millions of dollars, the Mars mission was developed for only about $25 million, through a process described by Indian officials as "frugal engineering."

...

The orbiter most definitely exceeded expectations. Originally designed for a lifetime of six months, it returned data back to Earth for nearly eight years.

The Universe Is Not Locally Real, and the Physics Nobel Prize Winners Proved It

Quote:
One of the more unsettling discoveries in the past half century is that the universe is not locally real. “Real,” meaning that objects have definite properties independent of observation—an apple can be red even when no one is looking; “local” means objects can only be influenced by their surroundings, and that any influence cannot travel faster than light. Investigations at the frontiers of quantum physics have found that these things cannot both be true. Instead, the evidence shows objects are not influenced solely by their surroundings and they may also lack definite properties prior to measurement. As Albert Einstein famously bemoaned to a friend, “Do you really believe the moon is not there when you are not looking at it?”

This is, of course, deeply contrary to our everyday experiences. To paraphrase Douglas Adams, the demise of local realism has made a lot of people very angry and been widely regarded as a bad move.

So this leaves a question about the non-local universe, or the Universe. Is there one true Universe? Many true Universes? Or no true Universe?

Do we even have a gender before we've been observed? If I have not met Nothing before, is their gender in a superposition until I do? Hahaha.

Planets don't exist

Hank and John Green's first ever shared educational video. Which also happens to be exceedingly adorable. I do feel some embarrassment with how much I admire a pair of rich, educated, white American men. At least they're doing good with what they've got.

Pedant alert:
The plural of fish is fish.
`That school of fish as many fish in it`

The plural of fish **species** is fishes
`There are many species of fishes, and of each species there are multiple fish`

So technically, we are all fish.
We are not all fishes because we are all one species (although that is debateable these days)

Unless, of course, "we" refers to tetrapods, or mammals, or some superordinal category along those lines, which, given the context of the video talking about a large number of different species, and the way that they are all fishes, isn't at all implausible.

The video title uses fish.
You used 'we' and 'fishes' whilst posting on here - ergo on here the context of we is NZG posters - unless there are other species that also use nzg?

I mean, ultimately, the reason I wrote it the way I did is because at some point in the NZG past, there was someone who had (iirc) "Cladistically speaking, we are all fishes." in their signature, or on the little title under their name, or something like that, and this video discussing it reminded me of that.

Of course, that's just how I remember it, and there's no guarantee I'm remembering it correctly, I didn't bother to look it up.

USSF-44 Mission

SpaceX launch out of the Florida sea mist.

T-01:00 (ish)

After leaving the secret payload to go and do its stuff:

Boostback

Double sonic booms on the return is awesome.

Double booster landing back at the cape.

I think I like the unsynchronised landing better - you can see the front one from the seconds on board camera.

Thumbs up

"We just heard... sonic booms" would make a great sample in a spacewave track, if you could get a clean version.

This is epic af, thank you for posting, Stoolie. There is something about watching the FH side boosters landing that buzzes me right out

The company seems to be performing well overall:

SpaceX is now building a Raptor engine a day, NASA says

Quote:
The Raptor rocket engine is crucial to Starship's success. Thirty-three of these Raptor 2 engines power the Super Heavy booster that serves as the vehicle's first stage, and six more are used by the Starship upper stage. For a successful lunar mission, these engines will need to re-light successfully on the surface of the Moon to carry astronauts back to orbit inside Starship. If the engines fail, the astronauts will probably die.

"SpaceX has moved very quickly on development," Kirasich said about Raptor. "We've seen them manufacture what was called Raptor 1.0. They have since upgraded to Raptor 2.0 that first of all increases performance and thrust and secondly reduces the amount of parts, reducing the amount of time to manufacture and test. They build these things very fast. Their goal was seven engines a week, and they hit that about a quarter ago. So they are now building seven engines a week."
I wonder what the next big milestone for space is. One has to be extra-terrestrial mining, but that's probably still a ways off.

I mean, Musk has been fairly open about the target squarely being Mars.

I'm guessing the next milestone would be mars round-trip, then landing on Mars with SpaceX craft; then starting to deliver equipment.
