Is dark matter just dwarf galaxies?

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.

Does that exactly the same sentence in the first two paragraphs indicate an AI writer?

I stopped reading at that point.

I don’t think there are many black holes in Rome. But I suppose they really want to make sure.

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.

I love that “recurrent nova” is a phrase.

XeroxCool,

Novas can recur. Supernovas cannot

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.

WWJD, do astronomy w Stunning James Webb images show birth and death of massive stars

Janus coming for us

huginn, do astronomy w Stunning James Webb images show birth and death of massive stars

I wish they had links to the full res in the article. Annoying to have a “stunning image” but it’s only a 1080x1080 jpg

If it's not seen as much, that probably means the green material is heavier than iron. It's less common, but large enough stars can fuse even heavier elements. That's where all those elements on Earth came from in the first place.

Fiivemacs, do astronomy w Giant volcano discovered on Mars

I dunno about giant. Looks pretty small from here.

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

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.

This fortune points to Trump 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.
