Hubble’s Inside the Image: Lensed Supernova Refsdal - YouTube - NASA Goddard - astrophysics
Albert Einstein predicted gravitational lensing,the warping of spacetime by the gravitational pull of massive objects such as galaxies.Gravity is actually a curvature in spacetime and can have the effect of enabling observation of very distant objects.This can also be used to ascertain how fast the universe is expanding.

Practicing Artemis Moonwalks in the Desert on This Week @NASA – May 17, 2024 - NASA Johnson Space Center
1.NASA Astronauts Kate Rubins and Andre Dawson simulated Artemis moonwalk missions in the Arizona desert near Flagstaff.The simulation involved technology demonstrations and hardware checkouts.*The VIPER robot lunar rover recently passed a system readiness test review,clearing it for environmental testing simulating the harshness of space.It will be launched prior to human lunar landings.*The NASA/ESA Hubble Space Telescope zeroed in on a young variable star in the constellation Taurus,HP Tau.The star is part of a three star system.This type of star hasn't begun nuclear fusion yet like our Sun.It is typically less than 10 million years old,while the Sun is about 4.6 billion years old (astrophysics).*The Polar Radiant Energy in the Far Infra Red Experiment (PREFIRE) climate change satellite is slated for lauch no sooner than 22 May 2024.

Milky Way's core is 'venting' - Chandra X-ray Telescope sees it! - YouTube - Space.com - cosmology
Using the Chandra X-ray Telescope,scientists have discovered a chimney and exhaust vent 26,000 light years from Earth.The structures are in the center of the Milky Way and perpendicular to its spiral arms.Exhaust from the Milky Way's centrally located supermassive black hole,Saggitarius A*/Sgr A*,may be behind the formation of these structures and other massive galactic structures.*Cosmology is the study of the origin of the universe and its structures.

A journey to Proxima Centauri and its planet - YouTube - ESO - astrophysics
This video (silent) shows an artist's impression of a trip from Earth to Proxima b,the closest planet to our Solar System.As we leave our Solar System,we see the familiar constellation figures,including the Southern Cross (Crux) and the bright stars Alpha and Beta Centauri.We gradually close on a faint red star,Beta Centauri,the closest star to Earth and the faintest component of a triple star system.The final part shows the planet Proxima b,the closest exoplanet to our Solar System.

G5 Coronal Mass Ejection results in spectacular aurora displays in Georgia USA
Power grid:the power grid today is more resilient than it was during Quebec's 9 hour blackout in 1989.Mitigation meausures were put in place as soon as our grid opeators were notified of the GS.Being in Low Earth Orbit,they are somewhat protected by the Earth's magnetic field.
Astronauts and Cosmonauts:NASA says the ISS crew is safe and doesn't need to hide in their designated shelters at this time.
Satellites:satellites in Low Earth Orbit are slowed down by such events and could experience some problems affecting communications and navigation.

🌎 LIVE Oumuamua Interstellar Object | NASA's Eyes
The first known Interstellar Object,Oumuamua,was discovered on 19 October 2017 by Robert Weryk using the Pan-STARRS 1 telescope at Haleakala Observatory,Hawaai.Reddish in color,it is possibly a hyperbolic asteroid,though others have proposed it is a comet.It's classification is still a mystery.It is headed back out to interstellar space.In 2019,Interstellar Comet Borisov/21 was the second interstellar object discovered.You will note in the animation a track out to 90377 Sedna,a reddish dwarf planet beyond the orbit of Neptune.Spectroscopy has shown its surface to be mostly a mixture of solid ices of water,methane and oxygen,along with widespread deposits of reddish-colored tholins,a chemical make-up similar to other trans-Neptunian objects.Perhaps tholins are also giving Oumuamua its reddish color.
