“The moon really is its own unique body in the universe. When we have that perspective and we compare it to our home of the Earth, it just reminds us how much we have in common. Everything we need, the Earth provides, and that, in and of itself, is somewhat of a miracle.”
It’s been several months since I last posted…too much work and no play!
Until this past Sunday. Whew.
After a morning lecture about ancient Japanese myths and “deliberately forgotten” kings (maybe), I was grateful to be able to take a quick power nap…
…so that the family could go up a nearby mountain and watch the Geminid meteor shower. (By “mountain,” I mean about 640m/2100ft.)
After a brief lecture/quiz by a staff member at our local culture center, we stayed outside, lying flat on the ground, for over an hour. And, yes, it was cold, despite the sleeping bag and thermal underwear. I saw three shooting stars. Not nearly as many as I’d hoped.
After we got home and took evening baths, the kids went out on our second-floor balcony and found out that the night view was even better at home than on top of a mountain! At least they knew what to look for, thanks to the culture center event.
And by “meteor,” I mean the size of grains of rice. Look to the eastern sky, just a bit to the northwest of Orion, to find the Twins (Castor and Pollux in Greco-Roman mythology).
For more on the origins of the Geminids, check out the JAXA mission to Phaeton, the parent body asteroid. It’s DESTINY!
The Taurids meteor showers get their name because the shooting stars appear to stream from a point in the sky where the Taurus constellation is located. Taurid meteors can be seen from pretty much anywhere on the planet except the South Pole.
I waited too long to post this! The meteor shower peaked last week, but might still be visible. The Orionids ended already (they appeared to fall from, you guessed it, the constellation of Orion, while the Taurids came from Taurus.
If you can’t see them, not to worry: the Leonids are on their way from next week (falling from, right again, Leo).
Very imaginative, these names. At least it makes them easier to spot. ☄️
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.
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!
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?
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.
This is an artist’s impression of a young star surrounded by a protoplanetary disc in which planets are forming. An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to provide the first observation of water and other molecules in the inner, rocky-planet-forming regions of a disc in one of the most extreme environments in our galaxy. These results suggest that the conditions for rocky-planet formation, typically found in the discs of low-mass star-forming regions, can also occur in massive-star-forming regions and possibly a broader range of environments.
Because of its location near several massive stars in NGC6357, scientists expect XUE 1 to have been constantly exposed to a high ultraviolet radiation field throughout its life. However, in this extreme environment the team still detected a range of molecules that are the building blocks of rocky planets.
