Scientists find cluster of underwater lakes on Mars

Recent research published in Nature Astronomy reveals the discovery of subglacial lakes beneath Mars' south pole, using radar data from the Mars Express orbiter. Initially, a large lake was found, followed by three additional salty lakes. Despite Mars' low atmospheric pressure, which prevents surface liquid water, these lakes may exist due to high salt content. The conditions are similar to subglacial lakes on Earth, suggesting potential for life remnants from when Mars had a more hospitable climate.

What instrument was used to discover the subglacial lake on Mars?

• Mars Subsurface Exploration Device (MSED)

• Mars Orbital Radar System (MORS)

• Mars Surface Imaging System (MSIS)

• Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS)

Where is the initially discovered subglacial lake located on Mars?

• Near the North Pole

• In the Ultimi Scopuli region

• In the Valles Marineris

• On Olympus Mons

Why is it difficult for liquid water to form on the surface of Mars?

• Frequent meteor showers

• Extreme heat from the sun

• Lack of a substantial atmosphere

• High atmospheric pressure

What keeps the water in Martian lakes liquid despite low temperatures?

• Strong magnetic fields

• Constant volcanic activity

• Presence of salts

• High levels of radiation

What Earth location is mentioned as having subglacial lakes similar to those on Mars?

• The Great Barrier Reef

• Lake Vostok in Antarctica

• The Amazon Rainforest

• The Sahara Desert
