    A terrifying glimpse at one potential fate of our Milky Way galaxy has come to light thanks to the discovery of a cosmic anomaly that challenges our understanding of the universe.

    An international team of astronomers led by CHRIST University, Bangalore, found that a massive spiral galaxy almost 1 billion light-years away from Earth harbors a supermassive black hole billions of times the sun’s mass which is powering colossal radio jets stretching 6 million light-years across.

    That is one o...

    Oxygen discovered in most distant known galaxy

    March 21, 2025, Categories  Astronomy/Space

    Two different teams of astronomers have detected oxygen in the most distant known galaxy, JADES-GS-z14-0. The discovery, reported in two separate studies, was made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This record-breaking detection is making astronomers rethink how quickly galaxies formed in the early universe.

    Discovered last year, JADES-GS-z14-0 is the most distant confirmed galaxy ever found: it is so far away, its light took 13.4 billion years to reach us, meaning we see it as it was when the universe was less than 300 million years old, about 2% of its present age.

    The new oxygen detection with ALMA, a telescope array in Chile’s Atacama Desert, suggests the galaxy is much m...

    Latest dark energy survey data suggest possible variations in dark energy over time

    Latest dark energy survey data suggest possible variations in dark energy over time
    The Dark Energy Camera (DECam), fabricated by the Department of Energy (DOE), is mounted on the Víctor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO) in north-central Chile. Telescope construction started in 1969 with the casting of the primary mirror. The assembly at the Cerro Tololo mountaintop was finished in 1974. Upon completion of construction it was the 3rd largest telescope in the world, behind the 200-inch Hale telescope at Palomar Observatory in California and the BTA-6 in southern Russia, and was the largest in the Southern Hemisphere (a title that it held for 22 years). It was later named in 1995 in honor of Víctor M. Blanco, Puerto Rican astronomer and former director of CTIO. Credit: DOE/FNAL/DECam/R. Hahn/CTIO/NOIRLab/NSF/AURA

    JWST captures its first direct images of carbon dioxide outside solar system

    HR 8799
    The clearest look yet in the infrared at the iconic multi-planet system HR 8799. Colors are applied to filters from Webb’s NIRCam (Near-Infrared Camera). A star symbol marks the location of the host star HR 8799, whose light has been blocked by the coronagraph. In this image, the color blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to the 4.6 micron light.

    The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR8799, a multiplanet system 130 light-years away that has long been a key target for planet formation studies.

    The observations provide strong evidence that the system’s four giant planets ...
