The glowing veils of the aurora appear regularly in the sky above Earth and make for great images, but capturing this phenomenon on other planets has always been more of a challenge. Recent observations of Mars and Jupiter have now given scientists unprecedented views of these extraterrestrial aurorae that will help improve our understanding of other planets’ magnetic fields and the space weather weather they experience throughout our solar system.

After failing to make it past Earth orbit on March 31, 1972, the remains of a Venus mission launched by the former Soviet Union circled our planet for years and was given the name Cosmos (or Kosmos) 482. While the rocket stage and other pieces returned to Earth weeks later, the lander itself made an uncontrolled landing in the Indian Ocean over the weekend.

Women have long contributed meaningful scientific discoveries to the field of astronomy; however, men have primarily dominated the vocation. As of 2019, women earn about 40 percent of the Ph.D.s granted in the field of astronomy, but that has not always been the case. And there are many cases of women working in astronomy only to have their findings overshadowed or derided in some capacity.

Beyond our solar system, sub-Neptunes — gassy planets larger than Earth but smaller than Neptune — reign as the most common type of exoplanet observed in our galaxy. Despite their prevalence, no such planets exist around our Sun, so these worlds have remained shrouded in mystery. NASA’s James Webb Space Telescope (JWST) recently observed exoplanet TOI-421 b, whose unique atmospheric conditions are now enabling scientists to understand sub-Neptunes in unprecedented detail.

The NASA and European Space Agency’s Hubble Space Telescope snapped a mesmerizing shot of an astronomical oddball, known as Arp 184 or NGC 1961. This strange spiral galaxy’s single broad arm earned it a place in Halton Arp’s Atlas of Peculiar Galaxies, published in 1966. That structure, along with multiple past supernovae, makes it an interesting subject for astronomers. Arp 184 resides approximately 190 million light-years from Earth in the constellation Camelopardalis the Giraffe.

In the 35 years since the Hubble Space Telescope flew to space, it has taken pictures of comets, merging galaxies, planets, supernova remnants, and more. The first-of-its-kind telescope — a joint NASA and European Space Agency effort — was lofted aboard the shuttle Discovery on April 24, 1990. Since then it has made nearly 1.7 million observations, looking at approximately 55,000 astronomical targets.

Last month, the European Space Agency (ESA) released a huge dataset from its space telescope Euclid. The release featured three deep-field mosaics glittering with 380,000 galaxies and hundreds of examples where the light of distant objects is bent and magnified by the gravitational influence of massive galaxies. The mosaics were captured in the constellations of Fornax, Draco, and Horologium.

NASA’s Lucy spacecraft visited the asteroid 52246 Donaldjohanson on Sunday, April 20, coming within 600 miles (920 kilometers) of the object located in the inner region of the asteroid belt between Mars and Jupiter. The asteroid was named after the paleontologist Donald Johanson, who in 1974 co-discovered the first identified example of previously unknown type of hominid. They named the specimen “Lucy,” which is what the mission is named after.

Looking like a bird ready to take flight from atop a post, this dusty filament within the Eagle Nebula was recently captured in intricate detail by the Hubble Space Telescope. Also known as M16, this nebula lies some 7,000 light-years from Earth in the constellation Serpens the Serpent and surrounds an open star cluster. This pillar of cold gas and dust stretches 9.5 light-years long and is composed of cold hydrogen gas, which serves as material to create new stars.
