Pictures from space! Our image of the day

"Spiders" spotted on Mars

(Image credit: NASA/JPL/UArizona)

Thursday, April 30, 2020: Strange, spider-like features creep on the surface of Mars in this image taken by the High-Resolution Imaging Science Experiment (HiRISE) camera on board NASA's Mars Reconnaissance Orbiter. These spidery landforms are what scientists call "araneiform" terrain, which literally translates to "spider-like." The features arise because the Red Planet's climate is so cold that during the Martian winter, carbon dioxide freezes from the atmosphere and accumulates as ice on the surface. When that ice begins to thaw in the spring, that carbon dioxide sublimates back into the atmosphere, or turns from a solid to a gas, leaving behind deep troughs in the terrain as gas is trapped below the surface. — Hanneke Weitering

Wednesday, April 29, 2020: In a deep-space image featuring countless distant galaxies of all shapes and sizes, a tiny dwarf galaxy takes center stage. The small elliptical galaxy in the foreground of this new Hubble Space Telescope image is known as PGC 29388. It contains between 100 million to a few billion stars, which pales in comparison to our Milky Way galaxy, which has 250 to 400 billion stars. "As beautiful as the surrounding space may be, the sparkling galaxy in the foreground of this image from the NASA/ESA Hubble Space Telescope undeniably steals the show," Hubble scientists said in a statement. The image was released  on April 20, a few days before the telescope celebrated its 30th anniversary. — Hanneke Weitering

Friday, April 24, 2020: Happy birthday, Hubble! To celebrate the 30th anniversary of the launch of the Hubble Space Telescope, NASA released this new image of a "cosmic undersea world" that is teeming with stars and colorful clouds of interstellar dust and gas. The image features the giant red nebula NGC 2014 and its smaller blue companion NGC 2020, both located in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way located 163,000 light-years from Earth. Hubble scientists have nicknamed the image the "Cosmic Reef," because the large nebula "resembles part of a coral reef floating in a vast sea of stars," Hubble officials said in a statement. — Hanneke Weitering

Wednesday, April 22, 2020: Happy Earth Day from space! This stunning view of Earth rising above the lunar horizon was captured by NASA's Apollo 16 crew shortly before they landed on the moon 48 years ago. The astronauts snapped this picture, which appears to have been inspired by Apollo 13's famous "Earthrise" photo, on April 20, 1972, the same day the lunar module Orion touched down on the surface with NASA astronauts John Young, Apollo 16 commander, and lunar module pilot Charlie Duke. Command module pilot Ken Mattingly stayed in orbit during their 71-hour stay on on the surface. — Hanneke Weitering

Tuesday, April 21, 2020: A chain of SpaceX's Starlink internet satellites orbits over Earth's lime-green auroras in this photo captured by an astronaut at the International Space Station. The tiny satellite trails were captured on Monday (April 13) at 5:25 p.m. EDT (2125 GMT), as the station was passing over the southern Indian Ocean at an altitude of about 231 nautical miles (428 kilometers), NASA said in an image description. The satellites pictured here appear to belong to the fifth batch of approximately 60 satellites that SpaceX has launched for its new Starlink constellation, according to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who avidly tracks objects in Earth's orbit. The company plans to launch its seventh batch of satellites on Wednesday (April 22). — Hanneke Weitering

Thursday, April 16, 2020: The Hubble Space Telescope has captured this new view of a peculiar spiral galaxy with rings within its winding galactic arms. Known as NGC 2273, this galaxy is officially designated as a barred spiral, meaning that it has a central bar of stars and pinwheeling arms. But this galaxy also has several ring structures within its spiral arms. NGC 2273 hosts one inner ring along with two outer "pseudorings." Astronomers believe these rings were created by spiral arms appearing to wind up tightly into a closed loop. — Hanneke Weitering

Wednesday, April 8, 2020: The nearly-full Pink Moon rises over a cloud-covered Earth in this photo taken by an astronaut at the International Space Station. This photo was taken on Monday (April 6), one day before the supermoon, or a full moon that coincides with the moon's perigee, the closest point to Earth in its orbit. Because the full moon of April is traditionally called the Pink Moon, last night's supermoon has been referred to as the "Super Pink Moon." — Hanneke Weitering
 

Juno spots hazy clouds on Jupiter

(Image credit: NASA/JPL/SwRI/MSSS/Gerald Eichstädt)

Tuesday, April 7, 2020: Hazy clouds streak across Jupiter's northern hemisphere in this new image from NASA's Juno spacecraft. These long, thin cloud bands consist of haze particles that drift above the planet's underlying cloud features. While the cause of these wispy clouds is still a bit of a mystery, scientists believe the hazy features could be related to Jupiter's jet streams. "Two jet streams in Jupiter's atmosphere flank either side of the region where the narrow bands of haze typically appear, and some researchers speculate those jet streams may influence the formation of the high hazes," NASA officials said in a statement. T

he Juno orbiter captured this image during its 25th close flyby of Jupiter, also known as a perijove, on Feb. 17 at 12:29 p.m. EST (1729 GMT), when the spacecraft was about 15,610 miles (25,120 kilometers) from the planet's cloud tops. — Hanneke Weitering

Monday, April 6, 2020: Saturn's moons Rhea and Janus tango on opposite sides of the planet's famous ring system in this new color-enhanced image from NASA's Cassini orbiter. Rhea, Saturn's second-largest moon, is visible in the foreground, while the smaller moon Janus is pictured in the distance across the rings. Citizen scientist Kevin Gill recently processed this 10-year-old view of Saturn and two of its moons using calibrated red, green and blue filtered images captured by the Cassini spacecraft on March 28, 2010. — Hanneke Weitering
 

Hubble eyes a one-arm spiral galaxy 

(Image credit: ESA/NASA/Hubble/I. Karachentsev)

Friday, April 3, 2020: A new Hubble Space Telescope image reveals the peculiar structure of a spiral galaxy with only one starry arm rotating about its center. While most barred spiral galaxies are characterized by a distinct bar-shaped structure of stars centered on a galactic core, this barred spiral isn't like most others. Located 21 million light-years from Earth in the constellation Canes Venatici, this strange galaxy, known as NGC 4618, was first thought to be a star cluster when the astronomer William Herschel discovered it in 1787. Astronomers now think that gravitational interactions with a neighboring galaxy may have influenced this galaxy's shape. — Hanneke Weitering
 

Venus meets the Pleiades

Thursday, April 2, 2020: The bright planet Venus begins its trek past the Pleiades star cluster, also known as the "Seven Sisters," in this photo taken by astrophysicist Gianluca Masi of the Virtual Telescope Project in Italy on Wednesday (April 1). Venus, which reaches its greatest brightness of the year at the end of the month, will make a close approach to the Pleiades tomorrow (April 3), when the two objects will be in conjunction — meaning they share the same celestial longitude — for the first time in 8 years. During the conjunction, Venus will be just one-quarter of a degree southeast of Alcyone, the brightest star in the cluster. Look for the pair in the western evening sky. You can also watch a live stream of the encounter from the Virtual Telescope Project here, starting at 1:30 p.m. EDT (1730 GMT). — Hanneke Weitering
 

Webb telescope deploys its mirrors

(Image credit: Chris Gunn/NASA)

Wednesday, April 1, 2020: NASA's James Webb Space Telescope has successfully deployed its giant primary mirror, putting the new observatory one big step closer to being ready for launch in 2021. The entire 256-inch (6.5 meters) primary mirror assembly unfurled into the same configuration that it would be after deploying in space. This critical test took place in early March, right before NASA's centers shut down due to the coronavirus pandemic. Work on the Webb telescope was temporarily halted on March 20. It is scheduled to launch in March 2021, though even before the coronavirus pandemic, that date was expected to slip. — Hanneke Weitering

    The IOD image for yesterday of the Veil nebula is stunning! The graphics are such that it's almost as if it has an oil film on top. It has both 3D and texture feel to it.
