Best evidence of active lava flows spotted on Venus

By - June 24, 2015 3 Pictures

ESA's Venus Express spacecraft has found the best evidence yet of active lava flows on Venus. Earlier missions to Venus have shown that the surface bears the unmistakable scarring of fierce, ancient volcanic activity. However, prior to Venus express, no mission had been successful in directly imaging clues to contemporary volcanism. This quirk has baffled scientists for years, as it has long been assumed that Venus hosts an internal heat source, and that heat has to escape somehow.

Combination radio/radar imaging produces stunning view of Venus

By - March 16, 2015 2 Pictures
A team of astronomers combining radio data from the Green Bank Telescope, West Virginia, and data from the radar transmitter at the National Science Foundation's Arecibo Observatory, Puerto Rico, have compiled a stunning new view of Venus. Often described as Earth's twin due to its similar proportions, capturing high quality images of the inhospitable planet has traditionally been a challenging prospect thanks to extreme atmospheric conditions. However, by combining observations from the instruments to create a more complete picture of Venus, astronomers can begin to observe how this enigmatic celestial object evolves over time. Read More

Roscosmos video replaces our Sun and Moon with well known stars and planets

By - January 28, 2015 27 Pictures
At some point in their lives, who hasn't looked up at the sky and gazed in wonder at Earth's closest companion? Hanging a dizzying 384,400 km (238, 606 miles) above us, the Moon has stood like a silent sentinel throughout our species' short existence. It has enticed some to visit and inspired others to look to the universe beyond. The Russian space agency Roscosmos recently released series of videos shot from the perspective of Earth, showing us what it would look like if other planets and stars took the place of our Moon and Sun.

Venus Express mission ends as fuel runs out

By - December 16, 2014 1 Picture
The European Space Agency's (ESA) eight-year Venus Express mission has come to an end. Having already extended its lifespan to four times that originally planned, the unmanned orbiter has exhausted its fuel during a final attempt to further prolong its usefulness. According to ESA, the spacecraft can no longer hold the correct attitude to maintain communications with Earth and will soon burn up in the Venusian atmosphere. Read More

Astronomers use astro-comb to seek Earth-like exoplanets

By - October 19, 2014 2 Pictures
Astronomers looking for exoplanets are using a fine-toothed comb – a fine-toothed astro-comb, to be precise. And just to make sure it works, the first planet they’ll be looking for is Venus. Developed by astronomers Chih-Hao Li and David Phillips of the Harvard-Smithsonian Center for Astrophysics, the astro-comb uses a new spectroscopic device installed in the Italian Telescopio Nazionale Galileo in the Canary Islands that will detect the beclouded planet by its gravitational effect on the Sun as a test of a potentially valuable tool in the hunt for Earth-like planets beyond our Solar System.

Venus Express gets new lease on life by skimming Venusian atmosphere

By - July 28, 2014 5 Pictures
Facing the alternative of a fiery death, the ESA’s Venus Express orbiter has completed a daring maneuver that extended the life of the unmanned explorer by several months. Under command from Earth, the spacecraft spent a month skimming the outer edge of the Venusian atmosphere to alter its velocity and send it into a new orbit that will keep it operating until perhaps the end of the year.

Hubble to use Moon as giant mirror to observe Venus transit

By - May 9, 2012 5 Pictures
From Earth's perspective, on June 5 and 6, Venus will pass across the face of the Sun. By observing the tiny fraction of sunlight that passes through Venus's atmosphere using the Hubble Space Telescope, it is hoped that the planet's atmospheric makeup can be determined. Though we already know the nature of Venus's atmosphere, it is hoped the event will help astronomers hone techniques, already in use, that may one day help to identify Earth-like planets in far-away solar systems. The catch? Hubble cannot observe the Sun directly. Instead it will look at the Moon to observe reflected light. Read More
