Saturn, which was in opposition on June 27th, was captured by Hubble Space Telescope in a series of astonishing pictures, and now is the turn for Mars to move as close to Earth as it can be. The red planet is also closer to Earth than it has been since 2003.

While scientists first found this geological formation back in the 1960s, the discovery that the Medusae Fossae Formation is volcanic was only made recently.

Water (H2O) has always been known to exist on Mars, but not in liquid form. Were the huge canyons and valleys, such as Valles Marineris that cut across large swathes of the surface, carved from water, tectonic or volcanic activity for example?

Iran remains wary on Trump’s offer of talks
Kenyon says there will be some pressure on Iran to negotiate with the US - but he puts that in perspective. Why did the USA withdraw from the nuclear deal? Good for them.

However, according to the researchers, it could be pure water on Mars. The lunar eclipse takes place in three phases - Total, Partial and Penumbral.

There another odd thing that happens with Mars around the time of opposition. This strong radar reflection was interpreted by the study's authors as liquid water - one of the most important ingredients for life in the Universe. Currently, the company intends to send humans to Mars by 2024. Ice-covered oceans are believed to exist on Europa, Ganymede, Enceladus, Titan, Triton, and several other bodies in the Solar System. He points to Italian astronomer Giovanni Schiaparelli as one of the inspirations for our curiousness about Mars.

"This subsurface anomaly on Mars has radar properties matching water or water-rich sediments", says Roberto Orosei, principal investigator of the MARSIS experiment and lead author of the paper published in the journal Science.

Federal judge orders stop to release of 3-D-printed guns
Wilson responded to the latest legal battle on Twitter calling on Second Amendment advocates to fight for their online rights. Richard Blumenthal, D-Ct., display a photo of a plastic gun on Tuesday, July 31, 2018, on Capitol Hill in Washington.

"The distance between the Earth and Mars is shorter than it normally would be", said Mackay. In case some contamination happens, the result might be out of our expectation. Mars only comes close enough for this detailed viewing every 15 to 17 years. But that needs delicate preparations and trials, for decades or even longer. It's now summertime in Saturn's northern hemisphere and springtime in Mars' southern hemisphere. Its surface rich in iron oxide makes it appear red, which is how it got its name from the god of war.

As planetary geophysicist Kevin Lewis noted, "Mars wouldn't be almost this dusty if it wasn't for this one enormous deposit that is gradually eroding over time and polluting the planet". With the support of NASA, some U.S. private companies have even been thinking about plans for immigration to Mars. But finding an unfrozen patch in its liquid state has so far evaded detection by any overhead orbiter or planet-bound rover.

The ISA declared their discovery on Wednesday, but they have been working on that for about six years.

Ex-Trump campaign chief Paul Manafort goes on trial for bank fraud
Prosecutors are expected to say that his life of luxury did not match what he had declared on his tax returns. An acquittal would support efforts by Trump and his allies to portray the probe as a " witch hunt ".

Antonio Paris, an astrophysics professor at the St. Petersburg College, said Mars should be as bright as Venus for the next few weeks. Geologic evidence suggests that the south polar layered deposits covered an area approximately twice as large 3 billion years ago as they do today; thus, there was much more ice to melt.
