Confirmation of ancient lake on Mars builds excitement for Perseverance rover's samples      (via sciencedaily.com)     Original source 

Ground-penetrating radar on board NASA's Mars Perseverance rover has confirmed that the Jezero Crater, formed by an ancient meteor impact just north of the Martian equator, once harbored a vast lake and river delta. Over eons, sediment deposition and erosion within the crater shaped the geologic formations visible on the surface today. The discovery of lake sediments reinforces the hope that traces of life might be found in soil and rock samples collected by Perseverance.

Astronomers unravel mysteries of planet formation and evolution in distant planetary system      (via sciencedaily.com)     Original source 

TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of information on planet formation and evolution in a young solar system. Researchers used a variety of tools to compile radial velocity and transit timing variation readings to derive highly precise measurements of the exoplants' masses, orbital information and atmospheres.

'Old smokers' and 'squalling newborns' among hidden stars spotted for first time      (via sciencedaily.com)     Original source 

'Hidden' stars including a new type of elderly giant nicknamed an 'old smoker' have been spotted for the first time by astronomers. The mystery objects exist at the heart of our Milky Way galaxy and can sit quietly for decades -- fading almost to invisibility -- before suddenly puffing out clouds of smoke, according to a new study.

Polymer power: Researchers enhance the safety of lithium batteries      (via sciencedaily.com)     Original source 

Lithium-ion batteries face safety concerns as a result of internal separator issues which often lead to short circuits. Scientists have now developed a method to improve the stability and properties of separators with a layer of silicon dioxide and other functional molecules. Batteries employing these separators demonstrated improved performance and reduced growth of disruptive root-like structures, paving the way for high-safety batteries that can aid the adoption of electric vehicles and advanced energy storage systems.

Astrophysical jet caught in a 'speed trap'      (via sciencedaily.com)     Original source 

The microquasar SS 433 stands out as one of the most intriguing objects within our Milky Way. A pair of oppositely directed beams of plasma ('jets') spirals away perpendicularly from the binary systems disk's surface at just over a quarter of the speed of light. The H.E.S.S. observatory in Namibia has now succeeded in detecting very high energy gamma rays from the jets of SS 433, and identifying the exact location within the jets of one of the galaxy's most effective particle accelerators.

New method flips the script on topological physics      (via sciencedaily.com)     Original source 

The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.
