OSIRIS-REX is NASA's first asteroid sample return mission. It launched in September 2016 on a journey to explore a near-Earth asteroid called Bennu. In October 2020, the spacecraft ventured to the asteroid's surface and collected about 250 grams of material for delivery to Earth. The mission's thrilling finale will take place on September 24, 2023, as OSIRIS-REx releases a capsule containing the Bennu samples for touchdown in the Utah desert.

The Earth is heading to the SUN 🌞 will this be the end of all life on Earth ?

This nighttime view of Earth is a cloud-free view from space as captured by the Suomi National Polar Orbiting Partnership Satellite (Suomi NPP). Suomi NPP, a joint program of NASA and NOAA, obtained this nighttime image using the satellite's Visible Infrared Imaging Radiometer Suite (VIIRS). The day-night band on VIIRS detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to look for signals such as city lights, gas flares and forest fires. The new image is a combination of data acquired over nine days in April and thirteen days in October 2012. It took 312 satellite orbits and 2.5 terabytes of data to get a clear shot of every parcel of Earth's surface. This video uses night vision produced by NASA's Earth Observatory, processed by NOAA's National Geophysical Data Center and combined with Earth Observatory's version of Blue Marble: Next Generation.

Uranus & Neptune discuss what would happen if they change the sun for a black hole!

In the six decades since NASA was founded, space exploration has made many important discoveries about our universe. The space agency has helped uncover many unknown facts and potential events about our world, from planets to galaxies at the edge of the unobservable universe. The most recent sun is likely to destroy our world.

This artist's rendering reflects new discoveries about a star torn apart by a black hole. When a star orbits too close to a black hole, intense tidal forces rip the star apart. In these events, called "tidal destructions," some of the stellar debris is thrown outward at high speeds while the rest falls toward the black hole. This causes a distinct X-ray flare that can last for a few years. NASA's Chandra X-ray Observatory, the Swift Gamma-ray Burst Explorer, and ESA/NASA's XMM-Newton put together the various pieces of this astronomical puzzle in the oceanic disturbance event ASASSN-14li, which was found in an all-sky optical search. went. Automated Survey for Supernovae (ASAS-SN) in 2014 November. The event occurred near a supermassive black hole a few million times the mass of the Sun at the center of PGC 043234, a galaxy about 290 million light-years away. Astronomers hope to find more events like ASASSN-14li to test theoretical models of how black holes affect their environments. During a tidal disruption event, most of the star's mass-containing filaments collapse toward the black hole. Eventually these gaseous filaments coalesce into a smooth, hot disk that glows in X-rays. As the disc forms, its central region becomes very hot, driving a flow of material, called wind, away from the disc.

Did you know the sun is this big? Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface. Our Sun is a bright, hot ball of hydrogen and helium at the centre of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.
