Sagittarius B2: The dense galactic center to reveal the most active star factory in the Milky Way.
Sagittarius B2: NASA's James Webb Space Telescope has pierced the dense galactic center to reveal the most active star factory in the Milky Way.
Sgr B2 is located just a few hundred light-years from the supermassive black hole at our galaxy's center. It is an extreme environment.
Astronomers are puzzled by its efficiency. Compared to the rest of the Galactic Center, Sgr B2 is punching way above its weight class.

GREGOR telescope captures rare high-resolution images of 2025’s most powerful sunspot group
In a stroke of extraordinary timing and clear skies, scientists using the 1.5-meter GREGOR solar telescope in Tenerife have recorded the explosive evolution of two powerful X-class solar flares on November 10 and 11, 2025. These rare, high-resolution observations—spanning magnetic braids, penumbral distortions, and flare precursors—offer an unprecedented view into the heart of the sun’s most energetic active region of the year.

Europa Clipper Captures Stunning Image of Uranus from Space
On November 5, 2025, NASA's Europa Clipper was busy testing its Stellar Reference Units—star-tracking cameras used to keep the spacecraft oriented. In a single frame, covering just 0.1% of the sky, it captured a field of stars... and something else. A tiny, pale dot near the edge was actually the planet Uranus, floating 2 billion miles away.
