Astronomers Observe Death of Distant Galaxy

Astronomers Observe Death of Distant Galaxy

TEHRAN (Press Shia) – Astronomers have, for the first time, witnessed the death of a distant galaxy, which they describe as a "truly extreme event." - Science news - When all of the stars in a galaxy die, and new ones are no longer forming, the galaxy itself ceases to exist. This occurs when all of the galaxy's gas is ejected, making it impossible for new stars to form.According to a study...

Astronomers Make New, Definitive Estimate for Age of Universe

Astronomers Make New, Definitive Estimate for Age of Universe

TEHRAN (Press Shia Agency) – How old is the universe? Astronomers have been homing in on an increasingly precise estimate for its age for decades. Now, a new research paper based on observational data gives of the most precise estimations yet: 13.77 billion years old. - Science news - The research, which was published in the Journal of Cosmology and Astroparticle Physics, analyzed the oldest...

Astronomers Spot Elusive 50 Million-Light-Year-Long Thread Tied to Cosmic Web

TEHRAN (Press Shia) – At the very largest scale, the Universe consists of a "cosmic web" made of enormous, tenuous filaments of gas stretching between gigantic clumps of matter. - Science news - Or that's what our best models suggest. All we have seen so far with our telescopes are the stars and galaxies in the clumps of matter.So is the cosmic web real, or a figment of our models? Can we...

Astronomers Map Most Extensive Atlas of Milky Way Galaxy Yet

Astronomers Map Most Extensive Atlas of Milky Way Galaxy Yet

TEHRAN (Press Shia) – There are nearly 2 billion stars in our galaxy. At least that's what the most current map shows. Astronomers have mapped the most extensive atlas of our Milky Way galaxy yet, including the positions of each and every one of those stars. - Science news - The European Space Agency's Gaia space observatory also tracked the movement, colors and brightness of these stars as...

Astronomers Capturer Last Moments of Star Devoured by Black Hole

Astronomers Capturer Last Moments of Star Devoured by Black Hole

TEHRAN (Press Shia Agency) – Through constant vigilance and some good fortune, astronomers have managed to capture the moment a supermassive black hole in a galaxy 215 million light-years away tore a star apart. - Science news - Using telescopes from the European Southern Observatory (ESO) and other organisations around the world, astronomers have spotted a rare blast of light from a star...

Astronomers Find Evidence Planets Start to Form While Infant Stars Still Growing

Astronomers Find Evidence Planets Start to Form While Infant Stars Still Growing

TEHRAN (Press Shia Agency) – Astronomers have found compelling evidence that planets start to form while infant stars are still growing. - Science news - The high-resolution image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) shows a young proto-stellar disk with multiple gaps and rings of dust. This new result, just published in Nature, shows the youngest and most...

Astronomers Find Six Galaxies Trapped in Web of Supermassive Black Hole

Astronomers Find Six Galaxies Trapped in Web of Supermassive Black Hole

TEHRAN (Press Shia Agency) – With the help of ESO's Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. - Science news - This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes, one of...

Astronomers Reveal Most Extreme Planets Ever Discovered

Astronomers Reveal Most Extreme Planets Ever Discovered

TEHRAN (Press Shia) – Astronomers have taken detailed observations of an incredibly extreme exoplanet, detecting brutal surface temperatures in the region of 3,200 degrees Celsius (5,792 degrees Fahrenheit). - Science news - Those temperatures – measured by the European Space Agency's CHaracterising ExOPlanet Satellite (or CHEOPS) – are enough to melt all rocks and metals, and even turn...

Astronomers Detect Giant Planet Orbiting Dead Star

Astronomers Detect Giant Planet Orbiting Dead Star

TEHRAN (Press Shia Agency) – Around 80 light-years from Earth lies the white dwarf WD 1856, a dead star that entered the final stages of its life around 6 billion years ago. - Science news - This slow death is typically quite lonely. In the process of dying, some stars will drastically expand, becoming a huge "red giant," like Betelgeuse, and engulfing any of the planets orbiting close by....

Astronomers Spot Potential Sign of Life in Venus Atmosphere

Astronomers Spot Potential Sign of Life in Venus Atmosphere

TEHRAN (Press Shia) – Astronomers have detected a rare molecule in the atmosphere of Venus that could be produced by living organisms, according to a new study. - Science news - Two telescopes in Hawaii and Chile spotted in the thick Venusian clouds the chemical signature of phosphine, a noxious gas that on Earth is only associated with life, according to a study in Monday’s journal Nature...
