Stephans Quintet from Webb, Hubble, and Subaru

on Mon Jul 18 2022

OK, but why can’t you combine images from Webb and Hubble? You can, and today’s featured image shows one impressive result. Although the recently launched James Webb Space Telescope (Webb) has a larger mirror than Hubble, it specializes in infrared light and can’t see blue — only up to about orange. Conversely, the Hubble Space […]

Europa and Jupiter from Voyager 1

on Sun Jul 17 2022

What are those spots on Jupiter? Largest and furthest, just right of center, is the Great Red Spot — a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini’s likely notation of it 357 years ago. It is not yet known why this Great Spot is red. The spot toward the […]

Tycho and Clavius at Dawn

South is up in this dramatic telescopic view of the lunar terminator and the Moon’s rugged southern highlands. The lunar landscape was captured on July 7 with the moon at its first quarter phase. The Sun shines at a low angle from the right as dawn comes to the region’s young and old craters Tycho […]

Lubovna Full Moon

on Fri Jul 15 2022

On July 13 this well-planned telephoto view recorded a Full Moon rising over Lubovna Castle in eastern Slovania. The photographer was about 3 kilometers from the castle walls and about 357,000 kilometers from this Full Moon near perigee, the closest point in its elliptical orbit. Known to some as supermoons, full moons near perigee are […]

Webb s Southern Ring Nebula

on Thu Jul 14 2022

Cataloged as NGC 3132 the Southern Ring Nebula is a planetary nebula, the death shroud of a dying sun-like star some 2,500 light-years from Earth. Composed of gas and dust the stunning cosmic landscape is nearly half a light-year in diameter, explored in unprecedented detail by the James Webb Space Telescope. In this NIRCam image […]

Webb s First Deep Field

on Wed Jul 13 2022

This is the deepest, sharpest infrared image of the cosmos so far. The view of the early Universe toward the southern constellation Volans was achieved in 12.5 hours of exposure with the NIRCam instrument on the James Webb Space Telescope. Of course the stars with six visible spikes are well within our own Milky Way. […]
