Hubble Peers Into the Heart of the Milky Way Galaxy

Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy. So packed with stars, it is equivalent to having a million suns crammed between us and our closest stellar neighbor, Alpha Centauri. At the very hub of our galaxy, this star cluster surrounds the Milky Way’s central supermassive black hole, which is about 4 million times the mass of our sun.

Astronomers used Hubble’s infrared vision to pierce through the dust in the disk of our galaxy that obscures the star cluster. In this image, scientists translated the infrared light, which is invisible to human eyes, into colors our eyes can see. The red stars are either embedded or shrouded by intervening dust. Extremely dense clouds of gas and dust are seen in silhouette, appearing dark against the bright background stars. These clouds are so thick that even Hubble’s infrared capability could not penetrate them.

Hubble’s sharp vision allowed astronomers to measure the movements of the stars over four years. Using this information, scientists were able to infer important properties such as the mass and structure of the nuclear star cluster. The motion of the stars may also offer a glimpse into how the star cluster was formed — whether it was built up over time by globular star clusters that happen to fall into the galaxy’s center, or from gas spiraling in from the Milky Way’s disk to form stars at the core.

This picture, spanning 50 light-years across, is a mosaic stitched from nine separate images from Hubble’s Wide Field Camera 3. The center of the Milky Way is located 27,000 light-years away. The “snowstorm” of stars in the image is just the tip of the iceberg: Astronomers estimate that about 10 million stars in this cluster are too faint to be captured in this image.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

The Hubble's replacement, the James Webb Telescope is going to be amazing.

This next generation of telescopes are going to humbling.

 

Considering how hard we are working to eliminate ourselves from this planet, Earth also seems to be void of intelligent life.

I like the creative names for the telescopes.

Large, Very Large, Giant Magellan, European Extremely Large and Overwhelmingly large.

Just wait, when Donald Trump is President, we'll get Huuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuge MOTHER FUCKING Telescope.
