Bob_Robertson_IX , in Vera Rubin's Primary Mirror Gets its First Reflective Coating

What a great article! Very informative and easy to read.

The telescope sounds cool too! An 8.5 meter mirror?! And it's designed to be able to recoat it over time!

MindTraveller , in Astronomers discover two new Milky Way satellite galaxy candidates

Is dark matter just dwarf galaxies?

deblan , in OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)

@fossilesque beautiful!

Cokeser , in Mysterious Picture crowd of giant spiders on Mars, what's that?

TL;DR

Of course no spider aliens as the clickbait might insinuate.

These are cracks in the ice sheet caused by gases which when released to the surface bring dark material with them is spread on the ground in that manner.

Sunlight causes the carbon dioxide ice at the bottom of the layer to turn into gas, then build up and break the ice sheets on it. The gas explodes in the spring on Mars, dragging dark material to the surface over time and destroying the ice layer as thick as a meter."

autotldr Bot , in NOAA says ‘extreme’ Solar storm will persist through the weekend

This is the best summary I could come up with:


After a night of stunning auroras across much of the United States and Europe on Friday, a severe geomagnetic storm is likely to continue through at least Sunday, forecasters said.

"The threat of additional strong flares and CMEs (coronal mass ejections) will remain until the large and magnetically complex sunspot cluster rotates out of view over the next several days," the agency posted in an update on the social media site X on Saturday morning.

Large areas of the United States, Europe, and other locations unaccustomed to displays of the aurora borealis saw vivid lights as energetically charged particles from the Solar storm passed through the Earth's atmosphere.

Early on Saturday morning, SpaceX founder Elon Musk said the company's Starlink satellites were "under a lot of pressure, but holding up so far."

Should this storm intensify over the next day or two, scientists say the major risks include more widespread power blackouts, disabled satellites, and long-term damage of GPS networks.

When these coronal mass ejections reach Earth's magnetic field they change it, and can introduce significant currents into electricity lines and transformers, leading to damages or outages.

autotldr Bot , in Daily Telescope: The most distant galaxy found so far is a total surprise

This is the best summary I could come up with:


This telescope, launched 18 months ago now, had as one of its express goals to deliver insights about the early Universe.

The most straightforward way of doing so is to collect the faintest, most distant light that has spent the longest time traveling to reach Earth.

In some eye-opening new results, the telescope has found and confirmed the discovery of a very bright galaxy that existed just 300 million years after the Big Bang.

The galaxy may not have the catchiest name—it's JADES-GS-z14-0, after the JWST Advanced Deep Extragalactic Survey program—but in every other way, it's a remarkable find.

“All of these observations, together, tell us that JADES-GS-z14-0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe," the astronomers said.

"Its discovery has profound implications for the predicted number of bright galaxies we see in the early universe."

autotldr Bot , in Daily Telescope: Black holes have been merging for a long, long time

This is the best summary I could come up with:


It showcases the coming together of two massive black holes in the early Universe, just 740 million years after the Big Bang.

The discovery of this merger so early in the Universe indicates that the growth of these objects in the centers of galaxies occurred very rapidly.

Fortunately, Webb and its Near-Infrared Spectrograph are well positioned to observe the fast-moving dense gas characteristic of black holes accreting matter.

As they swallow nearby matter, black holes produce highly ionized gas.

"Our findings suggest that merging is an important route through which black holes can rapidly grow, even at cosmic dawn," said Hannah Übler of the University of Cambridge.

"Together with other Webb findings of active, massive black holes in the distant Universe, our results also show that massive black holes have been shaping the evolution of galaxies from the very beginning."

Rentlar , in This Is the sound of Mars from 140 million miles

Dry like the Mojave but windy like Chicago.

shortwavesurfer , in Is This The best way to set up the internet on Mars?

You absolutely must replicate as much data as you can in server rooms there instead of having to pull it from Earth via laser link and you must launch some sort of relay satellite at a 45 degree angle or whatever so that it can maintain contact during solar conjunction.

maculata , in How NASA's Roman mission will hunt for primordial black holes

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

Gotta say Astronomers being linked up through the internet is a powerful thing esp when we can combine our images

The number of galaxies present in JWST images always makes me want to puke
