There are many words that could be used to describe WASP-76b — hellish, scorching, turbulent, chaotic, and even violent. This is a planet outside the solar system that sits so close to its star it gets hot enough to vaporize lead. So, as you can imagine, until now, “glorious” wasn’t one of those words.
This planet (located in the constellation Pisces) seems to have a rainbow effect of concentric rings…despite being so hot that iron falls from the sky.
Researchers will fly rockets into the path of the eclipse, stand in zoos watching animals, send radio signals across the globe, and peer into space with massive cameras.
And you don’t need to be a scientist to take part.
If you’re lucky enough to have no clouds or rain, that is.
Things the eclipse affects:
Radio waves
Animal behavior
The birds and the bees (seriously; read about what tortoises did last time)
Things scientists can view thanks to an eclipse:
The solar wind (plasma on the surface of the Sun)
Coronal mass ejections (which interfere with satellites)
Dust rings around the Sun and possibly even new asteroids
The East Coast of North America, where most of my relatives live, is currently 13 hours behind me in Japan. So the event will be long over by the time I wake up.
Hope to see video of it on the morning news show tomorrow!
The eclipse begins as a small notch slowly appears along one edge of the Sun. During the next hour, the Moon gradually covers more and more of the Sun’s bright disk. You’ll need a Solar Filter to both view and photograph the partial phases.
On April 8, 2024, there will be a total solar eclipse across parts of North America. It starts on Mexico’s Pacific coast and ends on Canada’s Atlantic coast. (So, no, it’s not just “from San Antonio to the Canadian border” as one article puts it).
I’m a little jealous of friends and family in the path. The eclipse lasts for over four minutes this time — if you’re in the area, enjoy!
This time I figured out how to import the slides directly into mmHmm, and I managed to update my MacOS to Sonoma, which allowed me to use my USB mic (yay). But I also called Ceres a “moon” at some point (it’s not a Moon but a dwarf planet in the asteroid belt near Mars). Oops. Not enough time to edit that bit out or record it again, so just word to the wise! Always fact-check videos, folks. Enjoy!
The asteroids in question are Iris (124 miles / 200 km in diameter) and Massalia (84 miles / 135 km). Both are in the asteroid belt between Mars and Jupiter. Iris is about the size of the US state of Maryland, while Massalia is roughly the size of Connecticut.
Note that the same observatory also found water on the Moon, about a “12-ounce bottle” worth. Not nearly enough for a settlement, but where there’s surface water (albeit trapped in soil on the surface), there’s likely to be more underneath.
So, astronomers need to know both mass and diameter to determine whether a planet is truly similar enough to ours to host some form of Earth-like life. If the planet has a low mass and a large radius, it is likely like a so-called mini-Neptune with a gassy atmosphere and little rock. If it has a higher mass but a smaller radius, it’s probably a rocky planet like ours.
The possibility that TOI-715 b is rocky “would be exciting because that supports it being more of a habitable planet versus some sort of other world,” says Moran.
TOI-715 orbits a red dwarf star around 137 light years away, so we won’t be getting there any time soon. But after finding this planet last year, astronomers also are trying to confirm the existence of another smaller, closer to Earth-sized planet in the habitable zone (i.e., in an orbit that permits liquid water necessary for life to evolve).
And the name of the possibly new “sibling” planet?
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day.
It’s also thought that water on Earth is largely (or entirely) the result of comets and asteroids bombarding it (it remains debatable to what degree Earth already had water, but since when it formed the Earth was first molten lava and then dry as a bone, I think it far more likely that water came here from elsewhere, and science tends to agree).
I’ve already blogged about the origins of Bringer of Light, when I (finally) finished the first draft back in early September. In a sense, I’ve been constantly blogging the science behind the story.
But I haven’t discussed the characters at all. And despite what some old-fashioned writers may think (just finished a particularly badly-written snarky “why your books don’t sell” piece of trash that claimed science fiction shouldn’t have any emotions in it…say what? sorry not sorry), if the characters of a story aren’t interesting, there isn’t much point in reading a story.
So for the next couple of weeks, I’ll write a bit about the characters — the crew of the Artemis, the crew of the Sagittarius, the UN flunkies (sorry, career politicos) on Mars and Luna and so forth. There are lots of characters, and their interaction is complicated. Or is it?
I would get into my scifi influences at this point, but long blogs are slogs. So I’ll come back to that tomorrow!
Coffee time. Also to finish up at least one unrelated project and also the hardcover manuscript (which needs to be a different paper size than the paperback for some reason).
A study published this weekend in the journal Monthly Notices of the Royal Astronomical Societyproposes that the oldest star in the Milky Way is a faint white dwarf that is about 10.7 billion years old and shining roughly 90 light years away from Earth.
