Astronomers nail down the origins of rare loner dwarf galaxies
Boston MA (SPX) Sep 07, 2021
By definition, dwarf galaxies are small and dim, with just a fraction of the stars found in the Milky Way and other galaxies. There are, however, giants among the dwarfs: Ultra-diffuse galaxies, or UDGs, are dwarf systems that contain relatively few stars but are scattered over vast regions. Because they are so diffuse, these systems are difficult to detect, though most have been found tucked wi

Hubble discovers hydrogen-burning white dwarfs enjoying slow aging
Baltimore MD (SPX) Sep 07, 2021
Could dying stars hold the secret to looking younger? New evidence from NASA's Hubble Space Telescope suggests that white dwarf stars could continue to burn hydrogen in the final stages of their lives, causing them to appear more youthful than they actually are. This discovery could have consequences for how astronomers measure the ages of star clusters, which contain the oldest known stars in t

Astronomers explain origin of elusive ultradiffuse galaxies
Riverside, CA (SPX) Sep 07, 2021
As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are their dark matter halos - the halos of invisible matter surrounding the galaxies - special?

NASA confirms Perseverance Mars rover got its first piece of rock
Washington (AFP) Sept 7, 2021
NASA confirmed Monday that its Perseverance Mars rover succeeded in collecting its first rock sample for scientists to pore over when a future mission eventually brings it back to Earth.
"I've got it!" the space agency tweeted, alongside a photograph of a rock core slightly thicker than a pencil inside a sample tube.
The sample was collected on September 1, but NASA was initially unsure

NASA's Perseverance rover collects first rock sample
Pasadena CA (JPL) Sep 07, 2021
NASA's Perseverance rover has completed the collection of the first sample of Martian rock, a core from Jezero Crater slightly thicker than a pencil. Mission controllers at NASA's Jet Propulsion Laboratory (JPL) in Southern California received data that confirmed the historic milestone.

Buttes on Mars may serve as radiation shelters
Mars has a "bad reputation" for its high exposure to radiation and it has neither a magnetic field nor a thick atmosphere to shelter its surface from high energy particles from outer space.
In a study published in Geophysical Research Letters, Guo Jingnan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, and international collaborators, analyzed the data from the Radiation Assessment Detector (RAD) on the Curiosity rover, and proposed a possible way to mitigate radiation on Mars.
The Curiosity rover launched in November, 2011 and landed on Mars in August, 2012. It was dedicated to searching for the elements of life on Mars. In September, 2016, Curiosity parked close to a butte and detected a reduction in radiation dose, and when Curiosity traversed far from the butte, the dose came back to normal. The researchers attributed this change in radiation dose to topographical variations.
They then plotted the panoramic sky visibility map of RAD for further investigation. They found that about 20% of the sky was blocked when Curiosity rover was near the butte, and the number was less than 10% before getting close to the butte, which suggested that surrounded buttes did shield a portion of radiation.
