What are Wormholes?

With all my enthusiasm for humanity's future in space, there's one glaring problem. We're soft meat bags of mostly water, and those other stars are really really far away. Even with the most optimistic spaceflight technologies ...

3-D visualisation redefines Milky Way's local architecture

Astronomers have used modern techniques to visualise data from ESA's Hipparcos space astrometry mission in three dimensions. The treatment of the data has offered insights into the distribution of nearby stars and uncovered ...

Robotically discovering Earth's nearest neighbors

A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at ...

Chemical fingerprints of ancient supernovae found

A Carnegie-based search of nearby galaxies for their oldest stars has uncovered two stars in the Sculptor dwarf galaxy that were born shortly after the galaxy formed, approximately 13 billion years ago. The unusual chemical ...

Guiding our search for life on other earths

A telescope will soon allow astronomers to probe the atmosphere of Earthlike exoplanets for signs of life. To prepare, Lisa Kaltenegger and her team are modeling the atmospheric fingerprints for hundreds of potential alien ...

An infrared atlas of interacting galaxies

Most galaxies, including our own Milky Way, have been influenced by an interaction with another galaxy at some time in their past. Interactions between galaxies can trigger an increase in star-formation activity as well an ...

The tell-tale signs of a galactic merger

The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714. This galaxy has drifted too close to another nearby galaxy and the dramatic interaction has twisted its spiral arms out of shape, ...

Hubble spies charming spiral galaxy bursting with stars

(Phys.org) —The NASA/ESA Hubble Space Telescope observes some of the most beautiful galaxies in our skies—spirals sparkling with bright stellar nurseries, violent duos ripping gas and stars away from one another as they ...
