The sun ejects a mid-level flare, rated M6.5, on April 2. NASA's Solar Dynamics Observatory captured the event in two wavelengths of extreme ultraviolet light.
M-class flares are a tenth as powerful as X-class events, the most intense flares our sun spits out. The flare also created a coronal mass ejection, which occurs when the sun belches a plume of superheated gas. A flare aimed directly at Earth can cause significant damage to electrical systems and satellites. (See "Solar Flare: What if Biggest Known Sun Storm Hit Today?")
Released on April 2 by the La Silla Observatory in Chile, this composite image of two galaxies reveals two very different life histories. The small spiral galaxy on the right, NGC 1317, has led a relatively peaceful life.
But its larger companion on the left, NGC 1316, bears scars from a violent past. Dust lanes embedded in a matrix of stars suggest that it gobbled up a spiral galaxy about three billion years ago. It has also ripped stars from their moorings and flung them into interstellar space, as evidenced by faint tidal tails—wisps of star matter that trail or precede a galaxy. (Get a closer look at NGC 1316's dust lanes.)
The View From on High
The Milky Way galaxy lights up the night above two ALMA radio telescopes in Chile's Atacama Desert. The altitude—16,400 feet (5,000 meters) above sea level—allows for exceptional visibility. The image was submitted to "The World at Night" by photographer Babak Tafreshi on April 1.
The surface of the moon is pockmarked with craters, punched by ancient collisions with asteroids or comets, in this image submitted to YourShot by Daniel McDonald on April 3.
The Fat One
A composite image released on April 3 combines x-ray data from the Chandra Observatory and optical data from the Hubble Space Telescope to form this brightly colored image of the galaxy cluster El Gordo—"the fat one" in Spanish. Information gathered from Hubble observations indicates El Gordo may be three million billion times the mass of our sun, or about 43 percent larger than researchers had thought.
The galaxy cluster, first discovered in 2012, is about seven billion light-years from Earth and is the most massive known galaxy cluster at that distance or beyond. Researchers think most of its mass is tied up as dark matter, colored blue in the image above.
Stargazers observe the night sky reflected in Lake Erken, 43.5 miles (70 kilometers) northeast of Stockholm, Sweden, near the end of March. The Andromeda galaxy is visible on the left.
I agree with Dr Diksha Sirohi, it would be helpful to beginner photographers to hear what cameras, what settings and what exposures were used.
Out there everything is mysterious and beautiful ,but is violent too. We the humans are so lucky because we are in the right position in the cosmos no to close and no to far from our star (sun).
Beautiful images..!! Makes one plan a visit to Chile & Sweden.. Can anyone also throw light on what sort of camera should be used to capture pictures like the one in Stockholm Sweden ?
I love all of them. Just finished watching the new Cosmo and this is what life is all about! Thanks for the great work!
Looking at these wonderful images in and around our universe just want to make me grow a pair of super wings, fly across and visit them before my time is done... !!!
These are beautiful, especially, the last one is never seen in modern city life.
I have never seen such kind of photos which is a lot of stars in the sky.
Love this images, especially the solar one - being an avid amateur astronomy who enjoys watching the sun in his scope.
Thank you for including my photo amongst all of these other photos which are, in my opinion, more than amazing.
@Daniel J. H. McDonald Daniel, your photo is every bit as amazing as the others. It is a unique, harsh and brilliant portrait of our Moon. Thank you.
