Red supergiant stars 'dance' because they have too much gas

And just a few days ago, no one knew it was coming. The asteroid, named 2022 NF, is expected to pass safely by our planet, according to calculations by NASA's Jet Propulsion Laboratory in Pasadena, California.

Scientists and divers made the new discoveries after creating the first phases of a precise digital 3D model of the shipwreck, which sank near Antikythera, a Greek island in the southern Aegean Sea, in about the second quarter of the first century B.C. The digital model — which the scientists made with thousands of underwater photographs of the seafloor site, using a technique called photogrammetry — could help in the search for more pieces of the mysterious geared mechanism, the team said.

The moon will reach its peak at about 2:38 p.m. EDT (18:38 UTC) on Wednesday, but the Buck doesn't stop here; the moon will appear bright and full on Tuesday and Thursday night (July 12 and July 14), as well. Avid skywatchers may notice that the moon looks even larger and brighter than normal. That's because, for the third month in a row, the full moon will rise as a supermoon — or a full moon that occurs while the moon is around or at its closest point to Earth, also known as its perigee. This month, the moon reaches perigee at about 5 a.m. EDT (09:00 UTC) on July 13, just 10 hours before the full moon rises.

The dancing stars are known as red supergiants, enormous stellar objects that have swelled up and cooled down as they've neared the end of their lives. These stars are about eight times more massive than the sun and can have a diameter up to 700 times that of the sun, which would be the equivalent of the sun's surface reaching beyond the orbit of Mars (engulfing Mercury, Venus, Earth and the Red Planet in the process). However, despite their colossal stature, these slowly dying behemoths can be extremely challenging to locate with precision.

The dinosaur tracks, stamped into the sandstone and siltstone of ancient lake beds in the Junggar Basin of northwestern China, suggest that more than 200 million years ago, the reptiles had already adapted to survive the cold of the polar regions before a mysterious mass extinction event plunged the world into freezing darkness.

Rather, the cute-and-cuddly canine is actually a young wolf. In a new study aimed at understanding dog domestication, researchers analyzed the genome of the puppy, along with the genomes of 72 ancient wolves. The pup, which was found in the Siberian permafrost in 2018 and whose lineage has been debated ever since, was nicknamed "Dogor" and was fully intact, with pettable fur and unbroken whiskers. At first, scientists couldn't tell if the 18,000-year-old pup was a wolf or a dog, but the new analysis revealed that it was a wolf — and that it was not very closely related to the earliest dogs.
