Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data enough to discover details about the characteristics of those planets is quite another. Not an easy task. Astronomers have had some initial success, but now they have been able to create the most detailed weather map for … Read more
The Great Red Spot on Jupiter is one of the most recognizable features in the Solar System: a massive hurricane-like oval-shaped storm in the atmosphere of the gas giant planet. It has been observed by telescopes and spacecraft for centuries. How a storm much larger than Earth could persist for so long has been mystery … Read more
Auroras are one of the most beautiful natural phenomena on Earth, but they can be found on other planets in the solar system as well, notably the gas giants. New photos and video were released today, February 11, 2014, of just such displays on Saturn, which is already well known of course for its stunning rings and hexagonal … Read more
The planets and moons in our Solar System come in a wide variety of colours, and the natural beauty can be breathtaking. Now, the true colour of a much more distant planet has been seen for the first time – and it’s blue!
So far, thousands of exoplanets and exoplanet candidates have been found orbiting other stars. As well, astronomers have seen some exoplanets still in the process of formation, providing clues as to how our own solar system came to be. One of these recent “planet-under-construction” findings however is challenging current theories on planetary formation – it’s a planet which … Read more
Among the many exoplanets now being discovered, Fomalhaut B was considered something special – the first exoplanet to be directly photographed in visible light, by the Hubble Space Telescope, back in 2008. That is, until more recent studies suggested that it might not be real, not even a planet after all.
The Hubble Space Telescope has made new observations of a “waterworld” exoplanet which has a thick, steamy atmosphere. The planet, GJ1214b, orbits a red-dwarf star and is about 40 light-years from Earth. It is about 2.7 times larger than Earth, with an estimated temperature of 232 ºC (450 ºF). While it orbits too close to its star to … Read more
