New Hubble Image of Globular Cluster NGC 6496

This newly released Hubble image shows globular cluster NGC 6496, which is located about 35,000 light years away. This 10.5-billion-year-old globular cluster, NGC 6496, is home to heavy-metal stars of a celestial kind! The stars comprising this spectacular spherical cluster are enriched with much higher proportions of metals — elements heavier than hydrogen and helium, […]

Astronomers Suggest Possible Link Between Primordial Black Holes and Dark Matter

A newly published study from NASA’s Goddard Space Flight Center suggests a possible link between primordial black holes and dark matter. Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of […]

Cassini Image of Prometheus and Saturn's Rings

NASA’s Cassini Spacecraft views Saturn’s Rings and its neighboring moon Prometheus. Most planetary rings appear to be shaped, at least in part, by moons orbiting their planets, but nowhere is that more evident than in Saturn’s F ring. Filled with kinks, jets, strands and gores, the F ring has been sculpted by its two neighboring […]

Tycho's Supernova Remnant Chandra Movie Captures Expanding Debris From a Stellar Explosion

By combining the Chandra data with 30 years worth of observations, scientists have made a movie of the evolution of Tycho’s supernova remnant. When the star that created this supernova remnant exploded in 1572, it was so bright that it was visible during the day. And though he wasn’t the first or only person to […]

Implications of L1 Observations for Slow Solar Wind

Using newly processed observations, astronomers spot tell-tale signs that the slow solar wind passing Earth originated from a magnetic phenomenon known as magnetic reconnection. From our vantage point on the ground, the sun seems like a still ball of light, but in reality, it teems with activity. Eruptions called solar flares and coronal mass ejections […]

Cassini Views Saturn's Moon Epimetheus

Cassini gets a closer look at Saturn’s little moon Epimetheus. Life is hard for a little moon. Epimetheus, seen here with Saturn in the background, is lumpy and misshapen, thanks in part to its size and formation process. Epimetheus did not form with all of those craters in place — rather, bombardment over the eons […]

New Horizons Reveals Water-Ice Signature on the Surface of Hydra

NASA’s New Horizons Spacecraft reveals a distinct water-ice signature on the surface of Pluto’s outermost moon, Hydra. NASA’s New Horizons spacecraft has sent home the first compositional data about Pluto’s four small satellites. The new data show the surface of Hydra, Pluto’s outermost small moon, is dominated by nearly pristine water ice – confirming hints […]

Clues about Volcanoes Under Ice on Ancient Mars Revealed

New evidence from NASA’s Mars Reconnaissance Orbiter suggests that volcanoes erupted beneath an ice sheet on Mars billions of years ago. The research about these volcanoes helps show there was extensive ice on ancient Mars. It also adds information about an environment combining heat and moisture, which could have provided favorable conditions for microbial life. […]
