Pictures from space! Our image of the day

A "fluffy" spiral galaxy

(Image credit: ESA/NASA/Hubble/P. Erwin et al.)

Tuesday, March 31, 2020: While most spiral galaxies have clearly defined arms the twist around a galactic core, others have patchy spiral arms that are not clearly distinguishable and resemble cotton wool. Due to this wooly appearance, the galaxy NGC 4237, shown here in a new image from the Hubble Space Telescope, is classified as a "flocculent" spiral galaxy. Located 60 million light-years from Earth in the constellation of Coma Berenices, or "Berenice's Hair," NGC 4237 has been a target for astronomers, not because of its fluffy appearance, but because its bright central region may bear clues about how supermassive black holes form inside galaxies. — Hanneke Weitering

Comet Atlas blazes through the night sky

Image 1 of 2

Comet C/2019 Y4 Atlas is slowly brightening in the night sky as it gets ready to swing around the sun in a couple months. Astrophotographer Mike Cuffe captured these two images of the green comet through his backyard telescope on Monday (March 23). In the first stacked image, the comet appears a bit blurry as it moves across a fixed background of stars. For the second image, the telescope was fixed on the comet, so the background stars appear as short trails behind a sharper image of the comet. Comet C/2019 Y4 Atlas is expected to make its closest approach to Earth on May 23, about one week before it reaches perihelion, or its closest point to the sun. It will brighten dramatically during this approach, and it may become visible to the naked eye in late April or May.

Wednesday, March 25, 2020: The European Southern Observatory's Very Large Telescope (VLT) beams its laser guide star into the night sky over Chile, creating a beam of light that arcs above the Milky Way galaxy. Astronomers use giant laser beams like these to help their telescopes correct for the distortion caused by turbulence in Earth's atmosphere, which can make stars appear to twinkle. For observations at the VLT, astronomers rely on the Laser Guide Star Facility at the Paranal Observatory in Chile. Pictured in the foreground are four domes of the SPECULOOS Southern Observatory. — Hanneke Weitering

A galaxy with "hunger pangs"

(Image credit: ESA/NASA/Hubble)

Friday, March 13, 2020: A new Hubble Space Telescope image of the spiral galaxy NGC 1589 reveals the galaxy's bright central bulge, where a supermassive black hole is lurking in a group of tightly packed stars. The galaxy "was once the scene of a violent bout of cosmic hunger pangs," Hubble astronomers said in a statement

Located 168 million light-years from Earth in the Taurus constellation, NGC 1589 was discovered by William Herschel in 1783. "As astronomers looked on, a poor, hapless star was seemingly torn apart and devoured by the ravenous supermassive black hole at the center of the galaxy," the Hubble team said. Now astronomers are using Hubble to look for any evidence of stellar debris that was ejected when the star ripped apart. — Hanneke Weitering

Monday, March 9, 2020: This Dragon cargo ship marked the end of an era of sorts for private spaceship builder SpaceX when it arrived at the International Space Station today. The Dragon CRS-20 spacecraft seen here is the last SpaceX Dragon to be captured by a robotic arm and attached to the station. Future SpaceX Dragon resupply flights will use the company's new Dragon 2 version, which can dock itself at the station. 

NASA astronaut Jessica Meir unveiled this photo on Twitter after using the station's robotic arm to capture the Dragon capsule. She wrote: "From now on, SpaceX will automatically dock to station. This Dragon capsule has been on station 2 times prior - sustainability is paramount to future space exploration."   — Tariq Malik
 

A weird crater on Mars

(Image credit: ESA/DLR/FU Berlin)

Friday, March 6, 2020: A new image from the European Space Agency's Mars Express orbiter reveals an odd, misshapen impact crater on Mars known as Moreux crater. While most craters appear roughly circular in shape, the outline of Moreux crater is shaped more like a fried egg. The crater's dark walls appear ridged and rippled, while dark brown and black dunes are smeared across the crater floor. The tall peak in its center is a pile of material that was ejected from the Martian terrain when the initial impact happened a few million years ago. Moreux crater's contorted appearance  developed over a long period of time, as erosion, wind and glacial activity shaped the planet's surface. This image was created using data collected by the High Resolution Stereo Camera on Mars Express, when the spacecraft flew over the area in October 2019. — Hanneke Weitering

Merging storms spotted on Jupiter

(Image credit: NASA/JPL-Caltech/SwRI/Tanya Oleksuik)

Tuesday, March 3, 2020: Two white, oval-shaped storms in Jupiter's atmosphere have been spotted merging into one. NASA's Juno spacecraft caught these anticyclonic storms in the act using its JunoCam imager on Dec. 26, 2019, as the spacecraft was completing its 24th perijove, or close flyby of the planet. At the time, Juno was passing about 44,900 miles (72,200 kilometers) above Jupiter's cloud tops at a latitude of about 60 degrees south. 

NASA has been tracking the larger of the two merging storms for years, and scientists have watched it gobble up several smaller storms in the past, NASA said in a statement. It narrowly avoided a merger with this same storm just a few months before this image was captured, when the two made a close approach as they churned through the planet's turbulent atmosphere. — Hanneke Weitering
 

Hubble spots a galactic "traffic jam"

A new image from the Hubble Space Telescope features the barred spiral galaxy NGC 3887, with its long, winding arms and bright galactic core. The German-English astronomer William Herschel discovered this galaxy, which is located 60 million light-years away from Earth, about 234 years ago.

Monday, March 2, 2020: A new image from the Hubble Space Telescope features the barred spiral galaxy NGC 3887, with its long, winding arms and bright galactic core. The German-English astronomer William Herschel discovered this galaxy, which is located 60 million light-years away from Earth, about 234 years ago. At the time, astronomers didn't understand how such spiral arms could even exist, because they thought a galaxy's spinning core would eventually wind them up so tightly that the spirals would disappear. It wasn't until the 1960s that astronomers came up with an explanation.

"Rather than behaving like rigid structures, spiral arms are in fact areas of greater density in a galaxy’s disc, with dynamics similar to those of a traffic jam," Hubble officials said in a statement. "The density of cars moving through a traffic jam increases at the center of the jam, where they move more slowly. Spiral arms function in a similar way; as gas and dust move through the density waves, they become compressed and linger, before moving out of them again." — Hanneke Weitering
