Two Galactic Neighbors

While it's common for galaxies to coexist peacefully in the same cosmic neighborhood, these two galaxies are a bit too close for comfort. The galaxies NGC 6286 (right) and NGC 6285 (left), collectively known as Arp 293, are tugging at each other with their mutually strong gravitational attraction, dragging wisps of gas and dust out from the galaxies and into interstellar space. This causes the galaxies to appear "smudged" and blurred from our perspective on Earth. The Hubble Space Telescope captured this image of the galactic pair, which are located more than over 250 million light-years from Earth in the constellation Draco.

Tuesday, November 26, 2019: Looming some 135 million light-years from Earth in the constellation of Centaurus is the bright emission line galaxy NGC 3749, seen here in an image from the Hubble Space Telescope. Astronomers can learn a lot about a galaxy by studying its spectrum of light, particularly the wavelengths of light that are emitted or absorbed by elements it contains. NGC 3749 displays strong emission lines, which means that it is "bursting with star formation and energetic stellar newborns," the European Space Agency said in a statement. — Hanneke Weitering

Hubble Spots a Strange Spiral Galaxy

(Image credit: NASA/ESA/Hubble/A. Seth et al.)

Thursday, November 21, 2019: The spiral galaxy NGC 772, seen here in a new image from the Hubble Space Telescope, bears some striking similarities to the Milky Way galaxy that we call home, with its spiral arms, glowing core and dark dust lanes. But there are some key differences between NGC 772 and the Milky Way. 

For one, NGC 772 lacks the kind of bar-shaped structure of stars like the one that stretches across the center of the Milky Way. NGC 772 is classified as a peculiar, unbarred spiral galaxy, which means that it is "somewhat odd in size, shape or composition," according to NASA. Located about 130 million light-years away from Earth in the constellation Aries, NGC 772 is about twice the size of the Milky Way. — Hanneke Weitering
 

Bye Bye, Debris Shield!

The debris shield that once protected NASA's Alpha Magnetic Spectrometer from micrometeoroid impacts floats away from the International Space Station after two astronauts removed it and flung it into space during a spacewalk on Nov. 15. European Space Agency astronaut Luca Parmitano used special tools to remove 13 screws and 10 fasteners to release the debris shield, after which NASA astronaut Drew Morgan jettisoned the shield, tossing it toward Earth to burn up in the atmosphere. This was the first of four spacewalks that these two astronauts are conducting to repair the ailing particle detector experiment, which was not designed to be serviced by astronauts in orbit, making these some of the most challenging spacewalks ever.

Lunar Halo Over La Silla

Friday, November 15, 2019: A lunar "halo" lights up the night sky above the 3.6-meter telescope at the La Silla Observatory in Chile. This phenomenon happens when the moon is at an altitude of about 22 degrees above the horizon, where light refracts through icy cirrus clouds. "Light rays that do this tend to 'bunch up' at the angle that represents the least amount of deviation from their original path. For the particular shape of ice crystal lurking within the cirrus clouds, this minimum deviation angle happens to be around 22 degrees," ESO officials said in a description. — Hanneke Weitering

Hubble Spots a Cosmic Kaleidoscope 

(Image credit: NASA/ESA/E. Rivera-Thorsen )

Friday, November 8, 2019: When the Hubble Space Telescope turned its gaze toward the remote galaxy known as the "Sunburst Arc," it saw not one but 12 separate images of the lone cosmic object. That's because there's a massive galaxy cluster in the foreground warping the light with its intense gravitational pull. This illusion is known as gravitational lensing, a phenomenon that Albert Einstein first described in his theory of general relativity. "This 'funhouse mirror' effect not only stretches the background galaxy image, but also creates multiple images of the same galaxy," NASA officials said in a statement. — Hanneke Weitering

(Image credit: ESA/NASA/Hubble)

Friday, November 1, 2019: The spiral galaxy NGC 1706 may look a bit isolated drifting through the cosmos in this Hubble Space Telescope image, but this lonely galaxy has no shortage of neighbors. NGC 1706 belongs to a group of dozens of galaxies, all of which are held together by their mutual gravitational pull. It is located about 230 million light-years away from Earth in the constellation of Dorado, the Swordfish. — Hanneke Weitering
