Kohoutek 4-55 Offers a Glimpse of Our Sun’s Future

This Hubble image reveals the final act of celestial beauty before the long fade into cosmic history. Invisibly buried in the center of this colorful swirl of gas is a dying star, roughly the same mass as the Sun. As a star ages, the nuclear reactions that keep it shining begin to falter. This uncertain […]

Hubble Views HBC 1

Surrounded by dust, this new Hubble image shows the young forming star known as HBC 1. The star is in an immature and adolescent phase of life, while most of a sun-like star’s life is spent in a stable stage comparable to human adulthood. In this view, HBC 1 illuminates a wispy reflection nebula known […]

XMM-Newton Reveals High-Speed Gas Streaming from a Spiral Galaxy

ESA’s XMM-Newton reveals that winds around a supermassive black hole located 800 million light-years from Earth are moving at 23,000–33,000 km/s, about 10% the speed of light. ESA’s XMM-Newton has found a wind of high-speed gas streaming from the center of a bright spiral galaxy like our own that may be reducing its ability to […]

SOHO Views a Solar Tsunami

ESA and NASA’s Solar and Heliospheric Observatory celebrates twenty years of space-based science. After 20 years in space, ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, is still going strong. Originally launched in 1995 to study the sun and its influence out to the very edges of the solar system, SOHO revolutionized this field […]

New Image of Schiaparelli Basin from Mars Express

This image from ESA’s Mars Express features the small crater embedded in the northwestern rim of the Schiaparelli impact basin. All around is evidence for past water and the great martian winds that periodically blow. A 42 km-wide impact crater and numerous smaller craters straddle the northwestern rim of the 460 km-diameter Schiaparelli basin in […]

New Cassini Image of Saturn's Moon Enceladus

This new Cassini image helps reveal the different features of Saturn’s moon Enceladus. Enceladus is a world divided. To the north, the terrain is covered in impact craters, much like other icy moons. But to the south, the record of impact cratering is much more sparse, and instead the land is covered in fractures, ropy […]
