Photo of the Day Do underground oceans vent through canyons on Saturn's moon Enceladus? Long features dubbed tiger stripes are known to be spewing ice from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring. Evidence for this has come [...]

The Dark Tower in Scorpius

Photo of the Day In silhouette against a crowded star field along the tail of the arachnological constellation Scorpius, this dusty cosmic cloud evokes for some the image of an ominous dark tower. In fact, monstrous clumps of dust and molecular gas collapsing to form stars may well lurk within the dark nebula, a [...]

Fermi’s 12-year All-Sky Gamma-ray Map

Photo of the Day Forget X-ray vision — imagine what you could see with gamma-ray vision! The featured all-sky map shows what the universe looks like to NASA's Fermi Gamma-ray Space Telescope. Fermi sees light with energies about a billion times what the human eye can see, and the map combines 12 years of [...]

Supermoon Beyond the Temple of Poseidon

By |2024-08-20T09:09:06-04:00August 20th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day A supermoon occurred yesterday. And tonight's moon should also look impressive. Supermoons appear slightly larger and brighter than most full moons because they reach their full phase when slightly nearer to the Earth -- closer than 90 percent of all full moons. This supermoon was also a blue moon given [...]

A Solar Prominence Eruption from SDO

By |2024-08-18T09:09:15-04:00August 18th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day One of the most spectacular solar sights is an erupting prominence. In 2011, NASA's Sun-orbiting Solar Dynamic Observatory spacecraft imaged an impressively large prominence erupting from the surface. The dramatic explosion was captured in ultraviolet light in the featured time lapse video covering 90 minutes, where a new frame was [...]

Meteors and Aurora over Germany

By |2024-08-14T09:09:15-04:00August 14th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day This was an unusual night. For one thing, the night sky of August 11 and 12, earlier this week, occurred near the peak of the annual Perseid Meteor Shower. Therefore, meteors streaked across the dark night as small bits cast off from Comet Swift-Tuttle came crashing into the Earth's atmosphere. [...]

Giant Jet from the International Space Station

Photo of the Day What's that on the horizon? When circling the Earth on the International Space Station early last month, astronaut Matthew Dominick saw an unusual type of lightning just beyond the Earth's edge: a gigantic jet. The powerful jet appears on the left of the featured image in red and blue. Giant [...]

The Light, Dark, and Dusty Trifid

Photo of the Day Messier 20, popularly known as the Trifid Nebula, lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection [...]

Milky Way Behind Three Merlons

By |2024-08-07T09:09:10-04:00August 7th, 2024|Categories: NASA News, Uncategorized|Tags: , , , , , |

Photo of the Day To some, they look like battlements, here protecting us against the center of the Milky Way. The Three Merlons, also called the Three Peaks of Lavaredo, stand tall today because they are made of dense dolomite rock which has better resisted erosion than surrounding softer rock. They formed about 250 [...]

Gaia: Here Comes the Sun

Photo of the Day What would it look like to return home from outside our galaxy? Although designed to answer greater questions, data from ESA's robotic Gaia mission is helping to provide a uniquely modern perspective on humanity's place in the universe. Gaia orbits the Sun near the Earth and resolves stars' positions so [...]
