what the fuck made you want to do all that math
ok look it’s just one multiplication problem and then a bunch of dimensional analysis (in this case a couple division problems). what is with the fear of math on my dash today
Gigantic ring system around J1407b much larger, heavier than Saturn’s
Astronomers at the Leiden Observatory, The Netherlands, and the University of Rochester, USA, have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn. The ring system – the first of its kind to be found outside our solar system – was discovered in 2012 by a team led by Rochester’s Eric Mamajek.
A new analysis of the data, led by Leiden’s Matthew Kenworthy, shows that the ring system consists of over 30 rings, each of them tens of millions of kilometers in diameter. Furthermore, they found gaps in the rings, which indicate that satellites (“exomoons”) may have formed. The result has been accepted for publication in the Astrophysical Journal.
“The details that we see in the light curve are incredible. The eclipse lasted for several weeks, but you see rapid changes on time scales of tens of minutes as a result of fine structures in the rings,” says Kenworthy. “The star is much too far away to observe the rings directly, but we could make a detailed model based on the rapid brightness variations in the star light passing through the ring system. If we could replace Saturn’s rings with the rings around J1407b, they would be easily visible at night and be many times larger than the full moon.”
“This planet is much larger than Jupiter or Saturn, and its ring system is roughly 200 times larger than Saturn’s rings are today,” said co-author Mamajek, professor of physics and astronomy at the University of Rochester. “You could think of it as kind of a super Saturn.”
Giant tarantulas keep tiny frogs (Chiasmocleis ventrimaculata) as pets. Insects will eat the burrowing tarantulas’ eggs – so the spiders protect the frogs from predators, and in return the frogs eat the insects. Source
This has blown my mind for years. It’s so unreal. It’s almost the same exact reason humans and cats started living together.
Tiny frogs are tarantula housecats. A science fact seldom gets to sound that much like meaningless word salad.

IODINE
A scientist made the crystals above by taking advantage of iodine’s ability to sublime (convert directly from a solid to a gas) at ambient air pressure. Granular iodine was gently heated in one section of a closed vessel while another section was kept cold. The gaseous I2 molecules condensed onto the cold surface one at a time, arranging themselves into the repeating patterns of a crystal lattice. This recrystallization is a fast and effective way to purify iodine and other substances that sublime.

Analemma. The sun’s position in the sky, photographed from the same location at the same time of day throughout a year, forms an analemma. This shows the sun’s apparent swinging from its northernmost position, at the analemma’s uppermost point, at summer solstice, to its southernmost position/lowest point, at winter solstice.
Rosetta Finds Out Much About a Comet, Even With a Wayward Lander
Photographs and data from the European Space Agency’s Rosetta spacecraft have provided an unprecedented close-up examination of a comet, but there is one thing that has not shown up yet: the small lander that bounded to the surface in November.
Scientists working on the mission describe their initial observations of Comet 67P/Churyumov-Gerasimenko in seven articles published Thursday in the journal Science. “This sets the baseline for the rest of the mission,” said Matt Taylor, the project scientist.

On the surface of Comet 67P, there are even what looks like ripples of sand dunes like those seen on Earth and Mars. That appears befuddling, as a comet has no atmosphere — and so no wind — and only a wisp of gravity.
“You have to ask yourself, is that possible?” said Nicolas Thomas, a professor of experimental physics at the University of Bern in Switzerland and lead author of one of the papers. Dr. Thomas said that back-of-the-envelope calculations indicated that it might be plausible, with the jets of gas and dust acting as wind and the particles held together through intermolecular attraction known as the van der Waals force instead of gravity. “You can convince yourself you can make them move,” Dr. Thomas said. “It’s plausible, at least at the moment.”
