Star visibility eroding rapidly as night sky gets brighter

Washington (AFP) Jan 19, 2023
Light pollution is growing rapidly and in some places the number of stars visible to the naked eye in the night sky is being reduced by more than half in less than 20 years, according to a study released Thursday.
The researchers, whose findings were published in the journal Science, said the increase in light pollution - skyglow - that they found was much larger than that measured by sat

Los Angeles CA (SPX) Jan 23, 2023
NASA's Ingenuity Mars Helicopter has acquired new images using its high-resolution color camera. The camera, which is mounted in the helicopter's fuselage, was pointed approximately 22 degrees below the horizon during the flight. The image shows the tracks of Perseverance running alongside a rocky outcrop.
On January 19, 2023 (Sol 681 of the Perseverance rover mission), Ingenuity completed

Star visibility eroding rapidly as night sky gets brighter: study
Write a comment
Light pollution is growing rapidly and in some places the number of stars visible to the naked eye in the night sky is being reduced by more than half in less than 20 years, according to a study released Thursday.
The researchers, whose findings were published in the journal Science, said the increase in light pollution —skyglow—that they found was much larger than that measured by satellite observations of Earth at night.
For the study of the change in global sky brightness from artificial light, the researchers used stellar observations from 2011 to 2022 submitted by more than 51,000 "citizen scientists" around the world.

Exotic water ice contributes to understanding of magnetic anomalies on Neptune and Uranus
Write a comment
Sao Paulo, Brazil (SPX) Jan 22, 2023
Ordinary everyday ice, like the ice produced by a fridge, is known to scientists as hexagonal ice (ice Ih), and is not the only crystalline phase of water. More than 20 different phases are possible. One of them, called "superionic ice" or "ice XVIII", is of particular interest, among other reasons, because it is thought to make up a large part of Neptune and Uranus, planets frequently referred

Paris (ESA) Jan 22, 2023
"Trois, deux, un - et decollage!" This is how the last three seconds will be counted down in the control centre in Kourou, French Guiana, this April before one of the last Ariane 5 launch vehicles lifts off from Europe's Spaceport.

Sols 3718-3720: Go For Drilling at Encanto
Write a comment
Pasadena CA (JPL) Jan 22, 2023
In the previous plan, Curiosity conducted a preliminary assessment of the potential drill target "Encanto" (as seen in the above MAHLI image) and today we received the data. The drill preload test and contact science data look good, so we are GO for our third attempt to get a sample of this marker band.
Today's 3-sol plan includes the full drill on the first sol, followed by portion charac
