Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.

The first light in the universe

Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape consisting of bright blue stars surrounding a yellow-white concentration of central stars. This concentration has a diagonal line of stars across it, called a bar. The galaxy is tilted inward to our view from Earth. A white S-shaped line slightly across the top is the Hubble image of an asteroid hovering across the field of view.. It looks dashed because the image is a composite of several exposures of the asteroid flying like a race car. Credit: NASA, ESA, PG Martín (Autonomous University of Madrid), J. DePasquale (STScI).

This figure shows how CSOs are probably formed. When one massive star gets too close to a black hole (left), it is devoured. This causes the black hole to emit a very fast dipole jet (center). The jet extends outward and its hot edges glow with radio wave emissions (right). Credit: B. Saxton/NRAO/AUI/NSF

On the left the rising sun (the falcon-headed god Re) sails up Nut's leg. On the right the setting sun sails down its arms to the outstretched arms of Osiris, who will recreate the sun in the underworld during the night.

This map illustrates the paths of the moon's shadow across the US during the 2024 total solar eclipse. On April 8, 2024, a total solar eclipse will cross North and Central America and create a total path. During a total solar eclipse, the moon completely blocks the sun as it passes between the sun to Earth. The sky will darken as if it were dawn or dusk, and those standing in the total eclipse path may see the Sun's outer atmosphere (corona) if the weather permits.
