The Kid Should See This @tksst@universeodon.com

On this day in 1990: The Hubble Space Telescope launched, revolutionizing our view of the cosmos despite a famously flawed mirror. When first images came back blurry, #NASA discovered the primary mirror was too flat by just 25.4 nanometers. After a dramatic 1993 repair mission, Hubble began capturing the #space imagery that has changed our understanding of the #universe.

Composite shows portions of four Hubble images from left to right. First, the left half of Mars in shades of orange, blues, and browns. Second, a tiny portion of the Rosette Nebula shows very dark gray material against a translucent blue background. Third, a portion of planetary nebula NGC 2899 looks like the number three in shades of red and orange. Fourth, the center of barred spiral galaxy NGC 5335 has a milky yellow center that forms a bar surrounded by the beginnings of blue star-filled spiral arms.

Venus conjunct Saturn

(& Mercury, to make triplets)

— an extremely bright, wondrous sight in the pre-dawn Eastern sky here.

Planetary alignment is visible globally all week, with Venus shining brightest.
Crescent moon shares the sky with this glittering group; sun will rise just below it.

A simulation of all the planets, some above, some below the horizon, as currently seen from coastal NSW, Australia. Venus, Saturn and Mercury are very bright in the eastern sky, shortly before dawn.

The nature of sub-Neptunes is one of the hottest topics in exoplanetary science.

Temperate sub-Neptunes are of special interest because some could be #habitable.

But these #planets might instead be rocky worlds with thick, hot atmospheres.
