*Unveiling the Einasto Supercluster: A Cosmic Behemoth
Astronomers have unveiled one of the most massive superclusters ever observed, a colossal structure named the Einasto Supercluster. Comprising thousands of galaxies and a mass of 20 followed by 15 zeros in stars, this supercluster is a testament to the pioneering work of Jan Oort, whose 95th birthday coincides with the discovery. The Einasto Supercluster, stretching 360 million light-years across, provides new insights into the large-scale structure of the universe, challenging our understanding of galactic evolution and the gravitational forces at play in these vast cosmic metropolises.
*Humans Alter Asteroid's Path and Shape
In a groundbreaking mission, humans have altered the shape and orbit of an asteroid. NASA's DART spacecraft collided with the asteroid moon Dimorphos, not only knocking it off course but also reshaping its entire structure. This kinetic impact demonstration confirms our capability to deflect potentially hazardous asteroids and marks a significant milestone in planetary defense strategies. The aftermath of the collision has been meticulously analyzed, revealing a reshaped Dimorphos with a shorter orbital period and a new, elongated form.
*Hubble's New Glimpse into Jupiter's Stormy Atmosphere
The Hubble Space Telescope has captured stunning new images of Jupiter, offering a fresh perspective on the gas giant's turbulent weather systems. The iconic Great Red Spot, a storm large enough to engulf Earth, is showcased alongside other atmospheric phenomena. Despite its gradual shrinkage and color changes, the Great Red Spot still rages with high-speed winds, interacting with smaller vortices that may be influencing its longevity. Hubble's detailed observations continue to unravel the mysteries of Jupiter's dynamic climate and the forces shaping its grand tempests.
