When can you see a black hole, a tulip, and a swan all at once? At night — if the timing is right, and if your telescope is pointed in the right direction. The complex and beautiful Tulip Nebula blossoms about 8,000 light-years away toward the constellation of Cygnus the Swan. Ultraviolet radiation from young […]

What if Saturn disappeared? Sometimes, it does. It doesn’t really go away, though, it just disappears from view when our Moon moves in front. Such a Saturnian eclipse, more formally called an occultation, was visible along a long swath of Earth — from Peru, across the Atlantic Ocean, to Italy — only a few days […]

When this picture was taken in July 1994, Dr. Irene Duhart Long was director of the Biomedical Operations and Research Office at NASA’s Kennedy Space Center in Florida. She was responsible for the program management of the center’s aerospace and occupational medicine, life sciences research, environmental health programs, and the operations management of the life […]

Did you see it? One of the more common questions during a meteor shower occurs because the time it takes for a meteor to flash is similar to the time it takes for a head to turn. Possibly, though, the glory of seeing bright meteors shoot across the sky — while knowing that they were […]

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 from the robot Cassini spacecraft […]

The full Moon and Earth’s shadow set together in this island skyscape. The alluring scene was captured Tuesday morning, August 20, from Fiji, South Pacific Ocean, planet Earth. For early morning risers shadowset in the western sky is a daily apparition. Still, the grey-blue shadow is often overlooked in favor of a brighter eastern horizon. […]

The Dash 7 that will be modified into a hybrid electric research vehicle under NASA’s Electrified Powertrain Flight Demonstration (EPFD) project on display with its new livery for the first time. In front of the plane is an electric powertrain that magniX will integrate into the current aircraft to build a hybrid electric propulsion system. […]

There is a quiet pulsar at the heart of CTA 1. The supernova remnant was discovered as a source of emission at radio wavelengths by astronomers in 1960 and since identified as the result of the death explosion of a massive star. But no radio pulses were detected from the expected pulsar, the rotating neutron […]
