Guest, w Newly discovered 'cosmic unicorn' is a spinning dead star that defies physics: 'We have a real mystery on our hands'

Jasmine’s subtle beauty lies in its ability to arugula plant spacing bloom repeatedly with little fuss. It can handle summer heat gracefully and brings natural softness to rock gardens, pathways, or balconies.

Guest, w Newly discovered 'cosmic unicorn' is a spinning dead star that defies physics: 'We have a real mystery on our hands'

Radiates class with its well-blended composition. Projects a clean yet warm trail that suits both office wear and blu by ajmal personal moments.

Olap, w New interstellar object candidate heading toward the sun

fosstodon.org/ - this scientist reckons 0.2AU to Mars. Still 30m km. And thus about 100x further than the moon. But it only took Armstrong three days to do that distance!

Could we slingshot between the earth and the moon a probe to reach it’s relative solar velocity and chase it down? Does anyone know the bounds of that?

Geodad, w A rare chance to see two exploding stars is happening in the southern sky

These never seem to happen in the northern hemisphere.

Or maybe they do, and there’s so much light pollution that they never bother to report on them.

Yeah, we need fewer satellites really.

As for the rest, that’s not easily solved.

ericbejlic, (edited ) w Leaving Pluto in the dust: New Horizons probe gearing up for epic crossing of 'termination shock'

Equipped with functioning instruments and still transmitting data, New Horizons will provide scientists valuable insight into the edge of our local solar system, helping us understand the transition zone between solar and interstellar environments.

I’m pretty sure you wouldn’t be able to get a custom number plate of that star’s name.

cool nickname for an ursaring too

PalimpsestNavigator,

Sadly, I had to look that up. Ah, Pokémon… the gulf separating me from my generation.

don’t think much about it, just post where ever you want

Bitswap, w Stargazing Saturdays 2025-04-12

Seems like you’re on the west coast (USA). Me too.

I’m hoping I get to duck out for a bit and take it all in after bedtime and chores. I won’t be able to pull out a telescope tonight, but sometimes binoculars surprise me.

conditional_soup,

You probably won’t see much in terms of globular clusters in binos. I feel like you should be able to resolve the Leo triplet in them, though I expect it would be a challenge. Probably your best bet is the beehive cluster in Cancer, which should be near the Zenith, the little beehive cluster in Canis Major, and some of the easier double stars (the second star out from the cup on the handle of the big dipper- mizar and alcor- is great) and the Orion belt stars. Good luck!

SplashJackson, w 'Ravenous' Supermassive Black Hole is Captured Belching Out 'Food' Into the Universe

It can’t be that ravenous if it’s barfing all the time, or is this a bulimic black hole?

Kichae, w 'Ravenous' Supermassive Black Hole is Captured Belching Out 'Food' Into the Universe

Wow, I never see NGC 4945 pop up in the news, science or otherwise. I looked at it as part of my undergraduate thesis 20 years ago, so I’m always keeping an eye out for it, and almost every time I get a ping it turns out to be M88 or the Sculptor galaxy.

This is fun!

telescopeadvisor, w Beginner telescope suggestions

Hi there! For a beginner-friendly telescope under $200 that’s great for nebulae and galaxies in a Bortle class 3 sky, I’d recommend checking out the award-winning options from TelescopeAdvisor. The 2025 Telescope Advisor Awards highlight some fantastic manual scopes perfect for your needs—no smartphone apps required! Something like a 4.5-inch or 5-inch reflector with decent magnification could be ideal for spotting deep-sky objects in Southern California’s rural skies. Visit Award Winning Telescopes to see the top picks—well worth a look for your stargazing adventure!

nailbar, w Most Planets in the Cosmos Probably Don’t Orbit Stars

This post made me imagine a nightmare scenario where Earth is ejected and we can only helplessly watch as the sun becomes smaller and smaller.

thegr8goldfish, w Most Planets in the Cosmos Probably Don’t Orbit Stars

I flat out don’t accept the notion that some starts have no planets. As far as I am concerned, if we have 8 major plantes and on average, 40% of planets are ejected, we should assume the average number of starting planets is 11.

Neverclear,

This is like saying, “If a carbon atom has 12 electrons, and on average it forms 4 covalent bonds, we should assume all atoms start with 16 electrons.”

PrettyFlyForAFatGuy,

nice sample size of one you have there
