Featured in this new image from the NASA/ESA/CSA James Webb Space Telescope is the dwarf galaxy NGC 4449. This galaxy, also known as Caldwell 21, resides roughly 12.5 million light-years away in the constellation Canes Venatici. NGC 4449 has been forming stars for several billion years, but it is currently experiencing a period of star […]
Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar coronae are one of the few quantum mechanical […]

“I say that to my team, whenever I have an opportunity. I share with my team that they are enabling science and exploration for dozens of missions being supported by NSN. Initially it just seems like words, but once they start realizing [their contributions] are real, I can tell you those people don’t want to […]
What happens if you ascend this stairway to the Milky Way? Before answering that, let’s understand the beautiful sky you will see. Most eye-catching is the grand arch of the Milky Way Galaxy, the band that is the central disk of our galaxy which is straight but distorted by the wide-angle nature of this composite […]
Rain today! With a high of 16C and a low of 16C. 82 Humidity. 13 C currently. 6 Km/h Wind from Southeast.
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, […]
Partly Cloudy today! With a high of 19C and a low of 19C. 85 Humidity. 11 C currently. 8 Km/h Wind from Southwest.
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 […]
