The best day to see all seven major planets (yes, you read that right, all seven!) is Friday, February 28th.
The link will describe (and give pictures) of where to find them all in the night sky.
Finding Orion is the key to most of them. Knowing where the Pleiades are helps, too.
The next time this “parade” appears will be 2040, so fingers crossed for clear skies!

The planet Uranus and its five biggest moons may not be the dead sterile worlds that scientists have long thought.
Instead, they may have oceans, and the moons may even be capable of supporting life, scientists say.
Cue the jokes in five…four…three…
“So, you mean there really is life in…ah…”
Note that this is not from new data. It’s a re-analysis of what Voyager 2 sent back decades ago. Basically, it just had a bad day, with magnetic storms screwing up the scan.
Still…
There could be moons there that could have the conditions that are necessary for life, they might have oceans that below the surface that could be teeming with fish!
I think this is a bit of an exaggeration…

Using the new method, one metric tonne of lunar soil will be able to produce about 51 to 76 kilograms of water, equivalent to more than a hundred 500-millileter bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said.

The soil was from the 2020 expedition, which was the first in 44 years to bring back soil from the Moon.
Considering all of NASA’s problems, it looks like China will have a moon base years before the US does…and probably in prime resource locations as well.
And don’t forget that the hydrogen in the soil can also be used for rocket fuel. It would be a lot easier to launch ships to Mars and beyond without having to deal with Earth’s gravity…

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.

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!

Water molecules have been detected in asteroid samples returned to Earth, but this marks the first time that the molecules have been discovered on the surface of an asteroid in space. The team studied four silicate-rich asteroids using data from the now-retired Stratospheric Observatory for Infrared Astronomy(SOFIA).
https://www.popsci.com/science/water-asteroid-space/
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.
(See also https://www.swri.org/press-release/swri-scientists-identify-water-molecules-asteroids-the-first-time — the PopSci linked article above essentially plagiarised almost its entire text. Bad scientist, bad.)
Original article here: Arrendono et al. (2024) Detection of molecular H20 on nominally anhydrous asteroids. Planet. Sci. J. 5. 37 doi 10.3847/PSJ/ad18b8 – good luck trying to read it!

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.
https://www.astronomy.com/science/recently-discovered-super-earth-might-be-habitable/
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?
“TIC 271971130.02”
Uh. We gotta come up with cooler names, folks.
For starters, they orbit a dwarf star.

Astronomers have found three previously unknown moons in our solar system — two additional moons circling Neptune and one around Uranus.
https://www.nbcnews.com/science/space/astronomers-spot-new-tiny-moons-neptune-uranus-rcna140285
One takes nearly 27 years to circle Neptune.
The “new” moon of Uranus is only 8 kilometers (5 miles) in diameter.
And there are likely many more yet to be discovered.

The moment we’ve all been waiting for is nearly here!
Bringer of Light is finally set to be released on March 15, 2024! (Click the link to see a book synopsis and two brief excerpts; Smashwords also has an excerpt from the beginning chapters.)
Stop by Draft2Digital to see links to your favorite bookstore online!
UPDATE: I have some difficulty convincing D2D to distribute to Amazon. Therefore, I have decided to publish Bringer of Light directly on Amazon. Stop by here to order for Kindle (released March 15th). Paperback and hard cover are also in the works.

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.

The Milky Way is old. Like, really, really old. One of the oldest galaxies.
This is probably what will eventually happen to our solar system. That’s right, everything will turn to rubble and get sucked into the dying Sun.
So, given all that, there’s only one thing for it…
