Total Lunar Eclipse over TsΓ© Bit'a'Γ
Earth's shadow caused this week's total lunar eclipse. The Moon appeared red as sunlight passing through Earth's atmosphere scatters blue light more efficiently, letting red light illuminate the lunar surface.

Shapley 1: An Annular Planetary Nebula
Shapley 1, the Fine Ring Nebula in Norma, is a planetary nebula formed by a Sun-like star. Its annular shape is due to our top-down view of a binary central system: a white dwarf and companion orbiting every 2β¦

Webb and Hubble: IC 5332
Hubble (visible) and Webb (infrared) views of spiral galaxy IC 5332. Visible light shows dark dust lanes obscuring stars. Webb's infrared reveals this same dust glowing from emitted heat, offering new insight into galactic structure and evolution.

The Egg Nebula from the Hubble Telescope
Hubble's Egg Nebula shows a dying Sun-like star. Its core is hidden by dense dust, but light beams escape through holes made by high-speed polar jetsβa brief, mysterious phase in stellar evolution.

Planet Parade over Sydney Opera House
This week, spot Mercury, Venus, Saturn, & Jupiter in a global planet parade after sunset. They appear in a line because all planets orbit the Sun in nearly the same plane, the ecliptic. Look west.

Pleiades: The Seven Sisters Star Cluster
The Pleiades (M45), or Seven Sisters, is a famous star cluster 400 light-years away in Taurus. Easily visible to the naked eye, its intricate dust clouds are dramatically revealed in long exposures.

βThe surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting.β

B93: A Dark Interstellar Ghost
Barnard 93 (B93) is a dark nebula that blocks background starlight. Far from empty, its dense gas and dust, born from dead stars, will eventually condense to form brilliant new stars.

IC 2574: Coddington's Nebula
Dwarf irregular galaxy IC 2574 (Coddington's Nebula), 12 million light-years away, shows intense star formation. Turbulent regions of glowing hydrogen gas are churned by stellar winds and supernovae, triggering new stellar births.

Orion's Cradle
Orion's vast stellar nurseries, 1,500 light-years away, are actively forming new stars. This wide view captures the Great Orion, Flame, and Horsehead nebulae, with deep filters revealing pervasive, faint hydrogen gas and Barnard's Loop.

Tails of Comet WierzchoΕ
Comet C/2024 E1 WierzchoΕ is a one-time visitor, its hyperbolic orbit destining it to become an interstellar traveler. Photographed near closest approach to Earth, it displays a striking 5-degree ion tail.
