NASA astronomers are tracking asteroid 2024 YR4. Earth impact risk dropped to 0.28%, while lunar impact probability increased to 1%. Observations continue.

The ESA’s Euclid telescope captured a stunning Einstein ring around NGC 6505’s core, formed as the galaxy bends and magnifies light from a distant background galaxy through gravitational lensing.

The Sun’s magnetic field flips every 11 years, marking solar maximum, its most active phase, with intensified solar events, unlike Earth’s relatively stable magnetic field.
