Strange quark stars may have formed from lucky cosmic mergers

The universe may contain extremely dense and exotic hypothetical cosmic objects called strange quarks. As astrophysicists continue to debate the existence of quark stars, a group of physicists have discovered that the remnants of the neutron star merger observed in 2019 have just the right mass to be one of these strange quark stars. when …

NASA’s Webb Space Telescope captures a cosmic tarantula

Webb’s Near Infrared Camera (NIRCam) captured this mosaic image spanning 340 light-years. It offers a fresh look at the star-forming region of the Tarantula Nebula, which includes tens of thousands of never-before-seen young stars previously shrouded in cosmic dust. The most active regions are pale blue and appear to be twinkling with massive young stars. …

A new study confirms that gravity has remained constant throughout cosmic ages

A new study confirms that gravity has remained constant throughout cosmic ages

Astronomers have known for more than a century that the universe has been expanding since the Big Bang. During the first 8 billion years, the expansion rate was relatively stable, hindered by gravity.However, thanks to something like Hubble Space Telescope, astronomers have since learned that the rate of expansion has been accelerating around 5 billion …
