A new way to peer into the permanently shadowed craters on the moon, searching for deposits of water ice

Not all flashlights are created equal. Some are stronger, consume more power, or have features such as blinking or strobes. Some aren't even meant for humans, such as a new project that recently received funding from a NASA Institute for Advanced Concepts (NIAC) Phase I award. Designed by the Ultra Safe Nuclear Corporation (USNC), this flashlight doesn't emit visible light, but it does emit X-rays and gamma rays, and the researchers on the project think it could be useful for finding resources on the moon.
The key to this technology is a novel radioisotope that USNC developed that goes by the trade name EmberCore. It is a type of nuclear chargeable ceramic, similar to the radioisotopes contained in the radioisotope thermal generators used by Mars rovers such as Curiosity and Perseverance.
Webb unveils dark side of pre-stellar ice chemistry

The discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date has been announced by an international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.

Ingenuity's 40th flight on Mars tracks a rocky road
Monday, 23 January 2023 10:52 Write a comment
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.

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 Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes

In 2015, a submarine volcano in the South Pacific erupted, forming the Hunga Tonga Hunga Ha'apai island, destined to a short, seven-year life. A research team led by the University of Colorado Boulder and Cooperative Institute for Research in Environmental Sciences (CIRES) jumped on the rare opportunity to study the early microbial colonizers of a newly formed landmass and to their surprise, the Satellite mapping finds new colony of Emperor penguins

Satellite mapping technology has discovered another new colony of the highly threatened Emperor penguins in Antarctica, researchers revealed Friday.
The find, announced by the British Antarctic Survey (BAS) to mark Penguin Awareness Day, brings the total number of known emperor penguin breeding sites around Antarctica's coastline to 66.
It is the latest in a series of Emperor penguin bre AIR launches high-resolution sensing and electrical stimulation neural activity study

Star visibility eroding rapidly as night sky gets brighter: study
Sunday, 22 January 2023 14:20 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.
