Hubble Observes Galaxy ESO 174-1 ◉ The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust. This image is part of a collection of Hubble observations designed to better understand our nearby galactic neighbors. ◉ The observations aim to resolve the brightest stars and basic properties of every known galaxy within 10 megaparsecs. ▸A parsec is a unit used by astronomers to measure the vast distances to other galaxies – 10 megaparsecs translates to 32 million light-years – and makes astronomical distances easier to handle. For example, the nearest star to the Sun, Proxima Centauri, is about 1.3 parsecs away. In everyday units this is a staggering 25 trillion miles (40 trillion km)!

Scientists discover a ‘failed’ neutron star that destroyed an asteroid and then fired off a bright explosion

An artist's illustration shows a distant galaxy with an active quasar at its center. A quasar is exceptionally bright because it releases tons of energy that's generated as a supermassive black hole gobbles up gas, dust and celestial objects.

Coolest Rocky Exoplanet Ever: James Webb Reveals Surprising Atmosphere of TRAPPIST-1 C NASA’s James Webb Space Telescope has discovered that exoplanet TRAPPIST-1 c, despite being the same size as Venus and receiving similar radiation, does not have a thick carbon dioxide atmosphere, making it unlikely to be a Venus analog. The planet, which has the coolest measured temperature for a rocky exoplanet, might have formed with minimal water content. It either lacks an atmosphere or possesses a very thin one, and further research will investigate temperature variations on the planet and continue studying potential atmospheric conditions.

​Tryptophan, An Amino Acid Essential For Life, Has Been Found In Interstellar Space ◉Tryptophan is one of the 20 amino acids considered essential for the formation of proteins, which are key macromolecules for the development of life on Earth. ◉The data took into account from many regions of star and planet formation, but it was in one of the nearest and best known regions, the molecular cloud complex in Perseus, and in particular in the stellar system IC 348 where the combination of all the spectroscopic data from the satellite has allowed us to attain the máximum sensitivity and to identify lines which tryptophan produces in the laboratory. ◉The study also presents evidence that tryptophan-associated emission lines may also be present in other star-forming regions and suggests that its presence, and possibly that of other amino acids, is common in the gas from which stars and planets form. “It is likely that amino acids, the building blocks of proteins, may be enriching the gas in the protoplanetary discs and atmospheres of young, newly formed exoplanets and perhaps accelerating the emergence of life there” says Iglesias-Groth.

World Economic Forum offers new debris mitigation guidelines The World Economic Forum (WEF) has released a new set of guidelines intended to reduce the creation of orbital debris with the support of some, but not all, major satellite operators. — The Space Industry Debris Mitigation Recommendations document outlines recommendations to: ◉ Avoid collisions that can create debris by limiting the lifetime of satellites in orbit after they have completed their missions. ◉ Improve coordination among satellite operators. 🚫 Some major companies, though, have not signed on. They include SpaceX, which operates by far the largest satellite constellation with its Starlink system, and Amazon, which is developing its Project Kuiper constellation. Even some satellite operators that have espoused the importance of space sustainability, like Viasat, are not included.

​​Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. Life may be generated directly on a planet or satellite endogenously or be transferred to it from another body, through a hypothetical process known as panspermia. Environments do not need to contain life to be considered habitable nor are accepted habitable zones (HZ) the only areas in which life might arise. As the existence of life beyond Earth is unknown, planetary habitability is largely an extrapolation of conditions on Earth and the characteristics of the Sun and Solar System which appear favorable to life's flourishing. Of particular interest are those factors that have sustained complex, multicellular organisms on Earth and not just simpler, unicellular creatures. Research and theory in this regard is a component of a number of natural sciences, such as astronomy, planetary science and the emerging discipline of astrobiology. ━━━━━━━━━━━ ☢ Physics ⚡

Weighing a quasar's galaxy with precision ◉ A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique – the mass of a galaxy containing a quasar, as well as their evolution in cosmic time. Knowing the mass of quasar host galaxies provides insight into the evolution of galaxies in the early universe, for building scenarios of galaxy formation and black hole development. ◉ “The masses of host galaxies have been measured in the past, but thanks to gravitational lensing, this is the first time that the measurement is so precise in the distant Universe,” explains Martin Millon, lead author of the study and currently at Stanford University on an SNF grant.
