A team of scientists combined stellar locations from the Gaia mission with dust and cloud maps from the WISE and 2MASS catalogs to create amazing three-dimensional images of the California Cloud and Orion A Cloud
Mar 15th: Found: Metal-rich Star. Parents Being Sought
A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form.
Mar 8th: Plants Successfully Grown in Lunar Soil
Using a mere twelve grams of lunar soil returned by the Apollo missions, scientists have successfully grown plants in the lab. With a wealth of genetic data on hand, they can now analyze the changes to the plants and the soil.
Feb 28th: Differences Fall Away Like Sand On Titan
Using spherical grains called ooids, found on Earth in shallow, tropical waters, scientists have found a possible mechanism for the formation of hydrocarbon sand on Titan.
Feb 23rd: The Second Repeating Fast Radio Burst is Discovered
A second repeating fast radio burst was detected in 2019 by China’s FAST observatory and confirmed in 2020 by the Very Large Array. This latest discovery raises the possibility that there are two different types of FRBs
Feb 15th: Dealing with Potentially Hazardous Asteroids
A trio of asteroid-related stories crossed our emails this week: Bennu’s sample is on schedule for next year’s return, researchers have developed a tool to measure an asteroid’s density distribution, and 3200 Phaeton’s rotational period has accelerated.
Feb 9th: Quasar’s Light Echoes After 6.73 Years
Astronomers using the 1.2-meter Whipple Observatory to follow the brightness of a lensed galaxy for 14.5 years have calculated that the time delay between light arriving along the shortest and farthest paths is 6.73 years.
Feb 3rd: Climate Change: African Lakes Sequestering Carbon Dioxide
Today we look at a trio of climate change stories, which are mostly bad news, although one study has discovered that African lakes are doing more sequestering of greenhouse gases than emissions. Plus, the CAPSTONE launch, meteorite crystals, and this week in rocket history, a mission that launched… but failed.
Jan 24th: Pulsar Found Racing Through A Supernova Remnant
Researchers using the Chandra X-ray Observatory have found that a known pulsar is moving through a supernova remnant at over one million miles per hour
Jan 20th: Electrons Swirl Like Water Under Specific Conditions
Using etched tungsten ditelluride at nearly absolute zero, scientists have observed electrons swirling around like whirlpools, behaving as a fluid. The methods could be used to design low-energy devices. Plus, eavesdropping on aliens, machine learning on solar data, and some new observatories are in the works.
