The Orion Nebula, as seen through the Spitzer Space Telescope

This image from NASA’s Spitzer Space Telescope shows what lies near the sword of the constellation Orion — an active stellar nursery containing thousands of young stars and developing protostars. Many will turn out like our sun. Some are even more massive. These massive stars light up the Orion nebula, which is seen here as the bright region near the center of the image.

Vårt vackra universum #16

Antenngalaxerna NGC 4038 & 4039, 70 miljoner ljusår från jorden

Äntligen släpptes första bilden från ALMA – och vilken skönhet den är!

Humanity’s most complex ground-based astronomy observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), has officially opened for astronomers. The first released image, from a telescope still under construction, reveals a view of the Universe that cannot be seen at all by visible-light and infrared telescopes. Thousands of scientists from around the world have competed to be among the first few researchers to explore some of the darkest, coldest, furthest, and most hidden secrets of the cosmos with this new astronomical tool.

Aurora australis, fotat från ISS

Sydsken sett från ovan. (Ja, även de där tokiga jävlarna som bor på andra halvan av klotet får uppleva aurora när solguden vill dem väl. Sluta vara fördomsfull.)

Vårt vackra universum #13

NASA/Hubble ST - The Sleeping Beauty/M64

You are seeing the result of two galaxies colliding about a billion years ago.  The center, where you see white blaze, is rotating clockwise.  In the outer portion of the galaxy you see this black, gaseous area.  This area is rotating counter-clockwise.  Now, where the two regions meet, the “shear”, there is this incredible explosion of new, hot, blue stars.  That’s the result of the tremendous forces involved pushing and moving against each other.  Around those gorgeous blue stars, you’ll see pink emission nebulae.  This is where the light from the stars is shining into the interstellar gasses and dust, and reflecting this glorious pink color (which our Hubble picked up).

Vårt vackra universum #12

One of the grandest ground-based astronomy projects of the coming decade is taking shape in the arid desert of northern Chile. These antennas, each measuring 12 metres across, are part of a much larger array that will eventually be spread a distance of around 16 kilometres.

The Atacama Large Millimeter/submillimeter Array, or ALMA, is being constructed at an altitude of 5000 metres on the Atacama desert’s Chajnantor plateau, one of the driest places on the planet. This lack of moisture, combined with the thin atmosphere at high altitude, offers ideal conditions for observing the cosmos at the still mysterious millimetre and submillimetre wavelengths which are emitted by cooler objects.

Vårt vackra universum #9

These nine galaxies were observed by NASA’s Wide-field Infrared Survey Explorer. Infrared wavelengths have been translated into colors we can see, with the shortest wavelengths shown in blue and the longest wavelengths in red. The galaxy in the center is NGC 1398, a barred spiral. Clockwise from top left, the other galaxies are M51 (Whirlpool Galaxy), M81 (Bode’s Galaxy), M83 (Southern Pinwheel Galaxy), NGC 2403, IC342 (Hidden Galaxy), IC 4895 (Barnard’s Galaxy), NGC 5907 (Splinter Galaxy) and NGC 628.
