This planet will be extra bright tonight

This planet will be extra bright tonight”

This is a very important factor that significantly simplify missions to the red planet and its potential development. It's a celestial orientation known as Mars opposition.

Mars is now cold, barren and dry but it used to be warm and wet.

"This thrilling discovery is a highlight for planetary science and will contribute to our understanding of the evolution of Mars, the history of water on our neighbour planet and its habitability", added Dmitri Titov, ESA's Mars Express project scientist. "And also closer to the Sun than it has been in a long time", Gilmore said.

Whether microbial forms of life could lie within is a matter of debate.

Mars is very cold, but the water might have been kept from freezing by dissolved salts.

To be clear, there's no sign of any actual Martian microbes swimming around, and the environment is not obviously hospitable - the water at the base of the polar cap is estimated to be minus 90 degrees Fahrenheit, far below the typical freezing point of water.

However, it is rather hard to find liquid water under thick ice caps. Due to this finding, there is a clue that life might also be there.

Ground-penetrating radar uses the method of sending radar pulses towards the surface and timing how long it takes for them to be reflected back to the spacecraft, and with what strength.

The lead writer of the study, Roberto Orosei si and astrophysicist at National Institute of Astrophysics in Bologna and he cannot control his excitement. The reservoir, which is at least 12 miles across, was found by radar signals.

Indeed, the creation of dust on Earth is much different than it is on Mars.

However, Stillman, who was not involved in the research, said another spacecraft, or other instruments, need to be able to confirm the discovery.

"This suggests that something odd is going on here".

NASA reported, a new paper published in Science this week suggests that liquid water may be sitting under a layer of ice at Mars' South Pole.

This summer's night sky offers a journey around the solar system, with four brilliant naked-eye planets visible and accessible with the Calvin College Observatory telescope. 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? Hubble was used to observe the planet on June 6, 2018, when Saturn was only approximately 1.36 billion miles from Earth, almost as close to us as it ever gets.

"On Earth, where there's water, there's life".
