Jeredin, do astronomy w Lightest black hole or heaviest neutron star? MeerKAT uncovers a mysterious object in Milky Way

I’ve been studying the range of neutron stars for some time and I feel confident it won’t be too long until much of our evidence and observations will show that black holes, quasars, super massive black holes and the range of other black holes are very likely, more extreme neutron stars - if not quark-like stars or stellar quantum-like objects. For fun, I’ve been also been focusing on colloids, extreme condensates and their quantum/relativistic phases/states; very revealing interactions and emergent properties. Now if we could just better observe zero-point energy…

5714,

What is zero-point energy?

Evil_Shrubbery, do astronomy w Astronomers detect black hole 'starving' its host galaxy to death

To shreds spaghetti you say?

btaf45, do astronomy w Astronomers discover two new Milky Way satellite galaxy candidates

If the distribution of those nine satellite galaxies across the entire Milky Way is similar to what was found in the footprint captured by the HSC-SSP, the research team calculates that there actually may be closer to 500 satellite galaxies

WTF? I was thinking there were around a dozen or so.

They solved one conundrum just to find another. Too few dwarfs then too many.

rebelsimile, do astronomy w Event horizon: After photographing black holes, scientists are now making a movie

oh boy, get ready people. it starts with a movie, then it’s a debut single, then you’re buying the fanzines, the hats, the shirts. this ends in commemorative plates.

tate, do astronomy w Dark Energy Camera captures remains of a massive star that exploded nearly 11,000 years ago in huge gigapixel image
@tate@lemmy.sdf.org avatar

wtf is a “dark energy camera?” smh

This thing is just a mosaic of ordinary CCDs. I’m sure the name has something to do with it’s specific scientific goals, but that’s not explained at all in this article. They didn’t even attempt to make any kind of connection between the veil and dark energy. Or even between supernovae and dark energy.

Zaktor, do astronomy w Saturn's largest moon most likely uninhabitable

It feels like the title should be “uninhabited”. Life on earth doesn’t survive because we continue to be bombarded with nutrient carrying asteroids, it just needed them to kick it off. That few nutrients are likely to make it from the surface to the ocean means the genesis is unlikely to occur, but it doesn’t seem to make a decision about whether an unlikely genesis could survive, even if only in a small pocket of the ocean.

Balthazar, do astronomy w An astronomer's lament: Satellite megaconstellations are ruining space exploration

Starlink is causing problems, but it seems to me that this image was made in bad faith to oversell the case. The caption says it’s a combination of 29 separate exposures, but if those exposures were combined properly, you wouldn’t see the satellites (median combination does wonders, and there are more sophisticated techniques which do even better). Some streaks start at one chip edge and extend to another chip edge, without continuity across the focal plane. So it’s not at all clear just how this image was created. And why on earth is it not flat-fielded? Maybe this is just really sloppy image processing, but even amateurs can do far better than this, leaving the final combination with no satellites at all.

Looks like they forgot the C.A.T. module

zerozaku, do astronomy w Earth bids farewell to its temporary 'mini moon' that is possibly a chunk of our actual moon

What?! Nobody told me that we got a new moon.

acockworkorange,

We literally did, you just weren’t paying attention. That should teach you!

Murdoc, do astronomy w Huge star explosion to appear in sky in once-in-a-lifetime event

I wonder if there’s a way to get an alert or something so I don’t miss it. I tried searching for one but so far no luck.

Tiltinyall, do astronomy w Huge star explosion to appear in sky in once-in-a-lifetime event

The last reoccurrence was after 80 years in 1946, I wonder why they are expecting it 2 years early?

Annoyed_Crabby,

They did said “80 years or so” and “around 80 years”, maybe they did their calculation and predicted that this year is likely the time that it happen. They did give a huge margin of when it will happen though.

0v0,

According to Wikipedia:

In March or April 2023, it dimmed to magnitude 12.3. A similar dimming occurred in the year before the 1946 outburst, indicating that it will likely erupt between April and September 2024.

Pronell, (edited ) do astronomy w A NASA mission that collided with an asteroid didn't just leave a dent. It reshaped the space rock

Neat. Makes sense. An asteroid isn’t usually one chunk of rock but several chunks conglomerated.

You think you might break it up but you rearrange it instead.

At least that’s how my dumb ass read it.

JoMomma, do astronomy w An astronomer's lament: Satellite megaconstellations are ruining space exploration

You can just say Starlink, it’s the only one

Amazon is planning and implementing the same.
