Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Spiral Galaxy NGC 2997 from VLT
Credit: FORS Team, 8.2-meter VLT, ESO
Explanation: NGC 2997 is a grand design spiral galaxy. Its small nucleus and sprawling spiral arms give it a type Sc designation. NGC 2997, pictured above, is speeding away from us at about 1100 kilometers per second, which would place it at about 55 million light years distant, given current estimates of the expansion rate of our universe. NGC 2997 is thought to have a mass of about 100 billion times that of our Sun, but is probably less massive than our own Milky Way galaxy. NGC 2997 is not seen face-on - it is thought tilted by about 45 degrees. NGC 2997 is particularly notable for a nucleus surrounded by a chain of hot giant clouds of ionized hydrogen.

Astronomy Fun Fact:
Bright, hot young blue stars (massive and short-lived) trace out the spiral structure in such galaxies. Their lives are too short for them to move far from their origin in the dust and gas clouds that make up most of the mass in the arms.
Get on the APOD PING list!

Wow ! The Universe contains infinite beauty, doesn't it?
Thanks for the pingaroo !
An lots of food for pondering, reflecting and ingesting ...
I didn't know you were the eye inside of me
You were a secret essence both in body and soul
I asked you show me a symbol of you in this world
Suddenly I realized you were the whole universe.

Collisions muted by distance

Collisions muted by distance =8 syllables
Distance muted collisions =7 but it reads like past tense!
(only you 2T!) My philosophy on bonuses is...
A glass can be filled
quite carefully past its rim.
Then we use a straw!
A straw metaphor
Telling me to suck it up?
Rules are rules in life
Not made to be broken or
trifled with by men.
Cote has a class for
all aspiring poets here.
Rules are mere LANGUAGE!
Even Space/time has shrunk to
one field, Thanks ALBERT!
If Newton's Laws were
enforced by 2Trievers, then
We'd speak Japanese!
Belvedere its clear
Benefits from structure, that
Keeps the wild Ones read!
I'll toe your line here
APOD's Rulebook isn't so fat!
Rules don't run THIS THREAD!
Ah! OoooooHhhhh! Whoooaaaa! Boooteeful! :-D
