@ManishEarth LOL how about two galaxies merging?

rare

Also, why would they be relativistic?

TildalWave

well, according to some sources and observations, there's a tiny galaxy merging with Milky Way at the other end as we speak ... tilted 90° too

And we're of course on a collision course with Andromeda

astrobites: Beware the power of “Earth-like”

Scientists always need to be cautious about throwing around terms like "habitable zone" and "Earth-like," lest they mislead the public or even themselves.

NASA Image of the Day: NGC 6946: The 'Fireworks Galaxy'

NGC 6946 is a medium-sized, face-on spiral galaxy about 22 million light years away from Earth. In the past century, eight supernovas have been observed to explode in the arms of this galaxy. Chandra observations (purple) have, in fact, revealed three of the oldest supernovas ever detected in X-rays, giving more credence to its nickname of the "Fireworks Galaxy."

ManishEarth

A lot of ascii is validated out sometimes

ManishEarth

Because I know the chem teacher uses Win98, so... Anything's possible.

TildalWave

ASCII subscripts?

As in a year when SQL, Apache, etc. started accepting that kind of stuff? I've always thought it was standard since about 1648, but maybe not?

@Tildal Yup.

ManishEarth

@Undo It depends on the encodign and all

It's UTF-8

@Tildal Yeah, but sub, not super.

ManishEarth

hm. Why didn't he like the images? O_0

@Manish I don't think he quite understands that there are numbers between 90 and 0

@Manish Probably because they slow down his 1995 machine.

The problem is he likes to introduce requirements while he's grading papers.

TildalWave

0 = can't open it without crashing my PC

0 = I need a new machine.

Oh, and @Manish, I got told that if I ever publish anything, the 'standard' is to write it out uglyly (6^(7*8)...). Please tell me it isn't true :P

You have to remember my age.

Yes, but if he's telling you not to use formatted math in publications, and being a general dick, that's just unacceptable

But I am going to write a nice big review about him on my own domain at the end of the class.

I'm homeschooled. And my parents are pissed of at him :)

Anyway, they seem to be fluvial sediments, likely clay .. .which would make it a good target for in situ tests

@TildalWave answered

TildalWave

@UV-D Ah cheers! Yes, those are definitely fluvial sediments... the first image you used is actually also from the Jezero and serves as a direct example of such sedimentation on Mars (definitely water)... my guess is, the ridges are clay and slate forming out of clay and volcanic sand ... Nili Patera is a lava bed (caldera) ... their size is however interesting, with roughly 10m wide ridges which would make them about 5m tall

what I'm saying is, that it seems that the lake was shallowly over the crater edges

that could also explain why there isn't any ejecta around the craters

Oh, BTW I took the Jezero crater image off this HiRISE video: youtube.com/watch?v=dE7ABFhWKM8
