Alnitak and the Flame Nebula

What lights up the Flame Nebula? Fifteen hundred light years away towards the constellation of Orion lies a nebula which, from its glow and dark dust lanes, appears, on the left, like a billowing fire. But fire, the rapid acquisition of oxygen, is not what makes this Flame glow. Rather... Continue Reading →

Blue Dunes on the Red Planet

A sea of dark dunes, sculpted by the wind into long lines, surrounds Mars' northern polar cap and covers an area as big as Texas. In this false-color image, areas with cooler temperatures are recorded in bluer tints, while warmer features are... Continue Reading →

3D Ingenuity

The multicolor, stereo imaging Mastcam-Z on the Perseverance rover zoomed in to captured this 3D close-up (get out your red/blue glasses) of the Mars Ingenuity helicopter on mission sol 45, April 5. That's only a few sols before the technology demonstrating Ingenuity will attempt to fly in the... Continue Reading →

Threads of NGC 1947

Found in far southern skies, deep within the boundaries of the constellation Dorado, NGC 1947 is some 40 million light-years away. In silhouette against starlight, obscuring lanes of cosmic dust thread across the peculiar galaxy's bright central regions. Unlike the rotation... Continue Reading →

In, Through, and Beyond Saturn’s Rings

Four moons are visible on the featured image -- can you find them all? First -- and farthest in the background -- is Titan, the largest moon of Saturn and one of the larger moons in the Solar System. The dark feature across the top of... Continue Reading →

Veil Nebula: Wisps of an Exploded Star

Wisps like this are all that remain visible of a Milky Way star. About 7,000 years ago that star exploded in a supernova leaving the Veil Nebula. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to... Continue Reading →

The Surface of Venus from Venera 13

If you could stand on Venus -- what would you see? Pictured is the view from Venera 13, a robotic Soviet lander which parachuted and air-braked down through the thick Venusian atmosphere in March of 1982. The desolate landscape it saw included flat rocks, vast... Continue Reading →

NASA’s Juno Reveals Dark Origins of One of Jupiter’s Grand Light Shows

The gas-giant orbiter is illuminating the provenance of Jovian polar light shows. New results from the Ultraviolet Spectrograph instrument on NASA’s Juno mission reveal for the first time the birth of auroral dawn storms – the early morning brightening unique... Continue Reading →

Hypergiant Star Canis Majoris

This artist's impression of hypergiant star VY Canis Majoris shows the star's vast convection cells and violent ejections. VY Canis Majoris is so large that if it replaced the Sun, the star would extend for hundreds of millions of miles, between the... Continue Reading →
