Scientists have a rare opportunity to study planets as Mercury passes between the Earth and the Sun
Once every 13 years Mercury passes between the Earth and Sun in an event known as Transit. During Transit, Mercury is visible from the Earth and allows scientists to study a planet's orbit. Scientists may also be able to discover new planets and exoplanets outside our solar system during this event.

This is when and how the universe is expected to end
It’s not expected to happen anytime soon, but one scientist has calculated when the universe will end. The research, published in the journal Monthly Notices of the Royal Astronomical Society, notes that sometime over the “next few trillion years,” when the universe is dead as we know it, stars will continue to explode, not with a giant bang, but “very, very slowly fizzle. ”

Coronavirus lockdown has brought Earth’s vibrations to a halt
“This quiet period is likely the longest and largest dampening of human-caused seismic noise since we started monitoring the Earth in detail using vast monitoring networks of seismometers,” said seismologist Stephen Hicks, from Imperial College London in the UK. “The lockdowns caused by the coronavirus pandemic may have given us a glimmer of insight into how human and natural noise interact within the Earth,” Hicks said.

Earth’s Magnetic Field Weakens
Earth’s Magnetic Field Weakens
The Earth’s magnetic field is weakening between Africa and South America, causing problems for spacecraft and satellites, scientists with the European Space Agency (ESA) have said. “The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is developing vigorously,” said Jürgen Matzka, from the German Research Centre for Geosciences, in an ESA news release.

Mars and its Global Magnetic Field?
According to a recent study, Like Earth, Mars's global magnetic field is believed to have been the result of a dynamo effect caused by an action in its core. However, rock samples that were taken from three large Basins – Hellas, Argyre, and Isidis – which formed 3.9 billion years ago – led most scientists to the conclusion that the dynamo was inactive by this time
