Researchers at the University of Colorado at Boulder have discovered evidence of shorelines on Mars, indicating the presence of an ancient lake on the Red Planet. Found on a broad delta with a series of alternating ridges and troughs, the ...
Two teams of astronomers, one from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and one from the Paris Observatory, France, have recently used the European Southern Observatory’s Very Large Telescope to study Betelgeuse, the second brightest star ...
Recently, the world’s largest telescopes have been aimed towards Jupiter. The reason: observing a new, unexplained expanding spot on the giant planet, caused by the impact of a comet or an asteroid. The spot, which is changing from day to ...
In this simulated image of Saturn’s rings, color is used to represent information about ring particle sizes in different regions based on the measured effects of three radio signals. Three simultaneous radio signals of 0.94, 3.6 and 13 centimeter wavelength ...
Researchers from the University of Melbourne have revealed the origins of tiger stripes and a subsurface ocean on Enceladus, one of Saturn’s many moons. In addition to explaining these geological features, the study sheds light on the evolution of planets ...
NASA’s Hubble Space Telescope snapped this picture of Mars within a day of its closest approach to Earth. A large regional dust storm appears as the brighter, redder cloudy region in the middle of the planet’s disk. This storm, which ...
Researchers at the Instituto de Astrofisica de Canarias in Tenerife have captured spectroscopic information from light passing through the Earth’s atmosphere during a lunar eclipse that could greatly enhance our ability to discover extrasolar planets. This so-called “transmission spectrum analysis” ...
The European Space Agency (ESA) has launched the Herschel Telescope about a month ago; recently, it started delivering its first images. The pictures taken are of higher quality than most space images, allowing astronomers to improve their study of nearby ...
Researchers from Cornell University have confirmed that the mysterious Tunguska explosion was caused by a comet. In 1908, this explosion levelled 830 square miles of the Siberian forest. Now the new findings have been validated, strangely enough by the exhaust ...
The European Space Agency (ESA) and NASA have shut down Ulysses, one of the longest serving solar orbiters in history. Ulysses was the pioneer spacecraft to chart the space area above and below the poles of the Sun. Clocking in ...
