Starship Asterisk*

This should be called the Japan Nebula!

Here, it uses Clair de lune. But in APOD, the music is different. Can anyone tell me which piece it is exactly?

Just wanted to say, it's APOD's 29th birthday Thank you editors, for giving us almost 3 decades of astronomy pictures everyday!

This is an old image. I remember it well, and you can tell its age from one of its authors, Hubble Heritage . The Hubble Heritage Project started in 1998 and came to an end in 2016, and I don't think that the M66 image was one of the last pictures published by Hubble Heritage, either. It was publis...

A polite correction here:
As this chart is dated, I think it needs an update which adds Tiangong, as the ISS is no longer the only space station which is home to astronauts!

Given that something like 85% of high mass stars are part of binary systems, maybe the question to ask is why only 50% of WR stars are binaries? OK, so I ask: Why 85% of high mass stars are part of binary systems? One answer probably has to do with the formation process of high-mass stars. https://...

It is estimated that about 50% of Wolf-Rayet stars occur in binary systems. Proposed companions are another Wolf-Rayet star, or a compact companion such as a black hole or neutron star. There is some evidence for both of these scenarios, but conclusive observations have yet to be obtained. The only...

It's not just you. Todays APOD is completely blank - really is "open space"

Well, it's not so blank now!

Is it just me, or is the main APOD link (https://apod.nasa.gov/apod/astropix.html) not working today?

April 11? Which one? I guess the one in 2019?

But I can still see those wires!

AR 3664.

Yeah, I see it's now fixed

So is it 3664 or 6443?

In the big picture, no species can evolve for long if the old versions aren't eliminated. You need reproduction for adaptation and evolution, and you can't have reproduction without death in any system with limited resources. OK, let's say that hypothetically, some genetic mutations have made it po...

DNA gets damaged over time, toxins accumulate over time. Some pest, parasite, or disease will eventually win. And evolution doesn't favor organisms that don't die and make room for future generations. How can evolution favor an organism's death? In the big picture, no species can evolve for long if...

Well, they have a lifespan of a few hundred years, depending on conditions. Maybe it will be there for another 200. But not forever. Yes, but why a tree can't live forever? I mean, some have been living for more than a millennia. Why this tree can't live that long? DNA gets damaged over time, toxin...

Originally from that neck of the woods , I was curious too. :thumb_up: Thanks! Btw, it mentions that "based on its species and history, it will probably be there for another 100 years." Why 100 years? What will happen after that? Well, they have a lifespan of a few hundred years, dependin...

According to the mathematics that I learned, 36 + 31 = 67, which is 4 (four) more than 63, not 3 more. Of course, this could easily be a matter of rounding issues. But then, if the actual figures were known with greater precision, it would have been quite possible to supply those numbers instead of...

I went to a concert in Portland a couple of months ago. Walking from the parking space I walked past a large tree and noticed this plaque in front of it: PXL_20240211_205553559 (1).jpg The city has grown all around the tree; it's flourished and become quite large. Which is pretty neat...nice work, ...

I fear this is another "artist's representation" that is not very connected to reality. So what needs to change in order to make it more realistic? Here's another picture that I like a lot better: https://asterisk.apod.com/download/file.php?id=49622&t=1 Tidal disruption of star near b...
