New study provides novel insights into the cosmic evolution of amino acids
Wednesday, 31 May 2023 11:08
All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists from Japan uncovered new clues about the cosmic origin of this asymmetry. Based on the optical properties of amino acids found on the Murchison meteorite, they conducted physics-based simulations, revealing that the precursors to the biolog One-third of galaxy's most common planets could be in habitable zone

Our familiar, warm, yellow sun is a relative rarity in the Milky Way. By far the most common stars are considerably smaller and cooler, sporting just half the mass of our sun at most. Billions of planets orbit these common dwarf stars in our galaxy.
To capture enough warmth to be habitable, these planets would need to huddle very close to their small stars, which leaves them susceptible to Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'

A study led by researchers of the University of Liege and the CSIC - using observations from NASA's TESS telescope - presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth.
The discovery is the result of a close collaboration between European and American uni Astronomers detected two major targets with a single telescope - a mysterious signal and its source galaxy

Astronomers have been working to better understand the galactic environments of fast radio bursts (FRBs) - intense, momentary bursts of energy occurring in mere milliseconds and with unknown cosmic origins.
Now, a study of the slow-moving, star-forming gas in the same galaxy found to host an FRB has been published in The Astrophysical Journal. This is only the fourth-ever publication on tw Helium nuclei research advances our understanding of cosmic ray origin and propagation

Much of our understanding of the Universe and its mysterious phenomena is based on theoretical interpretations. In order to deepen the understanding of distant objects and energetic phenomena, astronomers are looking at cosmic rays, which are high-energy charged particles composed of protons, electrons, atomic nuclei, and other subatomic particles. Such studies have revealed that cosmic rays con GPS tracking reveals how a female baboon stopped using urban space after giving birth

A new study from Swansea University and the University of Cape Town provides the first documented evidence of a cessation in urban space use by a female baboon after giving birth: another example of how wild animals are adaptively responding to urbanisation.
The study, recently published in the journal Ecology and Evolution, used GPS collars to track the movements of 13 chacma baboons in C Second Axiom Space private astronaut mission concludes with splashdown

High winds halt Spanish rocket launch
Wednesday, 31 May 2023 07:46
The maiden flight of the Spanish-built Miura 1 rocket was canceled Wednesday due to high winds, startup PLD Space said, in a setback for development of the small-scale space launcher.
"We have no green light, there are gusts of wind at high altitude above our limits. That means we don't have sufficiently safe conditions to launch," a commentator said on PLD Space's livestream of the lift-off, which was to be Spain's first.
It will be several days before a new launch window opens, the commentator added.
Standing just 12 meters (40 feet) tall, the small rocket was to fly 100 kilometers (62 miles) above the Earth's surface from a military base in southern Spain.
While that distance would put it in outer space, the rocket is not powerful enough to reach orbit.
Wednesday's sub-orbital launch had been slated to bring a payload with micro-gravity experiments, as well as setting up PLD Space's plans for future rockets.
"The idea is to learn and to minimize risks for the first flights of the Miura 5", said PLD Space cofounder Raul Verdu, referring to a launcher the firm hopes will place satellites into orbit from 2025.
