Astronaut Eugene A. Cernan, lunar module pilot, egresses the Apollo 10 spacecraft during recovery operations in the South Pacific. U.S. Navy underwater demolition team swimmers assisted in the recovery operations. Already in the life raft were astronauts Thomas P. Stafford (left), commander; and John W. Young, command module pilot. The three crewmen were picked up […]
It’s back. The famous active region on the Sun that created auroras visible around the Earth earlier this month has survived its rotation around the far side of the Sun — and returned. Yesterday, as it was beginning to reappear on the Earth-facing side, the region formerly labeled AR 3664 threw another major solar flare, […]
Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and active star formation. They lie a mere 650 light-years away, at the boundary of the local bubble and the Chamaeleon molecular cloud complex. Regions with young stars identified as dusty reflection nebulae from the 1946 Cederblad catalog […]
What’s happened to our Sun? Nothing very unusual — it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space, producing an energetic coronal mass ejection (CME). The filament had been held up for days by the Sun’s ever changing magnetic field and the timing of the […]
Orbiting 400 kilometers above Quebec, Canada, planet Earth, the International Space Station Expedition 59 crew captured this snapshot of the broad St. Lawrence River and curiously circular Lake Manicouagan on April 11. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater. The […]
Helen Ling was a supervisor for the computing group at NASA’s Jet Propulsion Laboratory in the 1960s. She was influential in the inclusion of women in STEM positions at JPL. Ling encouraged women within the computing group to attend night school in order to obtain degrees that would allow them more professional opportunities within JPL. […]
Star formation can be messy. To help find out just how messy, ESA’s new Sun-orbiting Euclid telescope recently captured the most detailed image ever of the bright star forming region M78. Near the image center, M78 lies at a distance of only about 1,300 light-years away and has a main glowing core that spans about […]
NASA astronaut Kate Rubins places a sample marker in the soil before collecting a sample during a nighttime simulated moonwalk in the San Francisco Volcanic Field in Northern Arizona on May 16, 2024. A sample marker provides a photographic reference point for science samples collected on the lunar surface. via NASA https://ift.tt/JHS5RNK
Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic yarn. It lies some 70 million light-years away, south of bright star Regulus toward the faint constellation Sextans. Wound up spiral arms are pulled out into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 interact gravitationally. Eventually the galaxies […]
Present-day Island of Hawai’i coastal flood risk, with higher risk indicated in dark blue, was modeled to help the County of Hawai’i in their shoreline setback plan. Sea Surface Temperature Anomaly data from 2022 Group for High Resolution Sea Surface Temperature Moderate Resolution Imaging Spectroradiometer (MODIS) indicate low temperatures in the East (red) to high […]
