Looking into the Milky Way’s Heart — ISAAC observes the Galactic Centre
European Southern Observatory Picture of the Week | 22 Nov 2010
The centre of our own galaxy, the Milky Way, is again in the sights of ESO telescopes. This time it’s the turn of ISAAC, the VLT’s near- and mid-infrared spectrometer and camera.
From Chile’s Atacama Desert, site of the ESO observatories, the Milky Way offers magnificent views, particularly in the southern hemisphere winter, when the central region of our galaxy is most visible (see
eso0934). However, the Galactic Centre itself, located about 27 000 light-years away in the constellation of Sagittarius, hides behind thick clouds of interstellar dust, which appear as dark obscuring lanes in visible light, but which are transparent at longer wavelengths such as the infrared. In this image, the infrared observations clearly reveal the dense clustering of stars in the galactic core.
ESO telescopes have been tracking stars orbiting the centre of the Milky Way for more than 18 years, getting the highest resolution images of this area and providing a definitive proof of the existence of a supermassive black hole in the heart of our galaxy (read more in
eso0226 and
eso0846). Infrared flashes emitted by hot gas falling into the supermassive black hole have also been detected with ESO telescopes (see
eso0330).
This representative-colour picture is composed of images taken by ISAAC at near-infrared wavelengths through 2.25, 2.09, and 1.71 µm narrowband filters (shown in red, green and blue respectively). It covers a field of view of 2.5 arcminutes.

MR. PITT: Oh, this is very odd.
KRAMER: (looking at picture) Yeah, it's 3-D art. Computers generate 'em. BIG computers.
MR. PITT: Yes, I've heard about these. How do they work?
KRAMER: Well, you blur your eyes like you're starin' straight through the picture. And you keep your eyes unfocused. And then... (Kramer and Pitt stare at picture) Oh, oh, oh, YEAH!
MR. PITT: I don't see it.
KRAMER: Yeah, it's a spaceship, surrounded by planets, asteroids...
MR. PITT: I still don't see it.
ELAINE: Okay, Kramer, that's enough. Mr. Pitt has got work to do.
KRAMER: Ya' ever dream in 3-D? It's like the boogeyman is comin' right at you.
MR. PITT: A spaceship, where?
KRAMER: (pointing) Right in here. Just keep your eyes unfocused. (convulses in pain) Waahh! Oh, mama!
ELAINE: Kramer, what's wrong?
KRAMER: Mama!
ELAINE: Kramer, Kramer, are you okay?
KRAMER: I think I gotta go to the doctor! (exits) Oh, mama!
MR. PITT: (still staring at picture) How long does it usually take?

Bystander, I love your picture. Art, I don't know about yours. It's all YELLOW!

Wow! Supermassive black hole
The universe is very incredible!!

Hello,
the picture showing the heart of the galaxy is beautiful!
Nevetheless, i don't see the black hole. I can see only many stars, while i am looking for a black area
Is there a black hole at the heart of all the galaxies? Or is it an inner caracteristic of our galaxy?
Have a very good day,
Céline

There is thought to be a
supermassive black hole at the heart of nearly every galaxy.

That's impressing. Now i don't want to travel to the heart of a galaxy anymore
But it is strange we can see stars, instead of a black area. Or, maybe the stars we see in your picture are far away in front of the black hole.
Thank you a lot!

Since the Black Hole emits no visible light you wouldn't really see it. What you do see is the gradual increase in light of stars nearer the black hole. I believe the brightest area is the central region.
