Astronomers using the South African radio telescope array MeerKAT have detected a clear radio-frequency signal from the interstellar object #3I/ATLAS, bringing strong support to the idea that it is a natural comet rather than an artificial object. 1/

Researchers have developed a promising new method to probe whether all black holes conform to the predictions of Albert Einstein’s general relativity or might instead reflect alternative theories of gravity. 1/5

The interstellar object #3I/ATLAS has sparked fascination bc, as it approached the Sun, it behaved in unexpected ways, brightening & showing a bluish tint instead of reddening. But none of this requires a non-natural explanation. As the object nears the Sun, its surface ices begin to vaporize. 1/7

The horizon melts into veils of green, violet & gold that don’t quite belong to this world, but to a dream the cosmos lets fall upon the Earth.
For a moment, the cold turns warm, as if the air itself were holding an ancient promise.
And u realize there’s beauty that can’t be explained, only lived.

(Yes, Venus is hotter than Mercury, even though Mercury is closer to the Sun. Its thick carbon dioxide atmosphere traps heat through a strong greenhouse effect, while Mercury lacks an atmosphere to retain heat.)

Mars sometimes appears to move backward in the night sky due to retrograde motion, an optical illusion. This happens when faster-orbiting Earth overtakes Mars. As Earth passes, Mars seems to slow, stop, and move westward, although it's still moving forward in space. 1/3
