 Sir Roger Penrose: The man who proved black holes weren’t ‘impossible’  If you ever struggled with maths at school, you were in good company. Sir Roger Penrose, who on Tuesday won the Nobel Prize for Physics, would also scratch his head in class. “I was always very slow. I was good at maths, yes, but I didn’t necessarily do very well in my tests,” the Colchester-born (1931) laureate recalled….more

Planet Mars is at its ‘biggest and brightest’   Mars is at its biggest and brightest right now as the Red Planet lines up with Earth on the same side of the Sun. Every 26 months, the pair take up this arrangement, moving close together, before then diverging again on their separate orbits around our star…more

 Black hole breakthroughs win Nobel physics prize   Three scientists have been awarded the 2020 Nobel Prize in Physics for work to understand black holes. Sir Roger Penrose, Reinhard Genzel and Andrea Ghez were announced as this year’s winners at a news conference in Stockholm. David Haviland, chair of the physics prize committee, said this year’s award “celebrates one of the most exotic objects in the Universe”…more

Life on Earth: Why we may have the moon’s now defunct magnetic field to thank for it  The habitability of a planet depends on many factors. One is the existence of a strong and long-lived magnetic field. These fields are generated thousands of kilometres below the planet’s surface in its liquid core and extend far into space – shielding the atmosphere from harmful solar radiation….more

Volcanoes fuel gaseous atmosphere on Jupiter’s moon Io  What is creating the bubbling, gaseous atmosphere on Jupiter’s moon Io? Scientists think they finally have the answer: volcanoes. Io, the solar system’s most volcanically active world, is one of four Galilean moons — the four largest moons of Jupiter, which were discovered by Galileo in the 17th century — and one of 79 total known satellites around the planet…more

The first habitable-zone, Earth-sized planet discovered with exoplanet survey spacecraft   TESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of discovering small planets around the Sun’s nearest neighbors, stars bright enough to allow for follow-up characterizations of their planets’ masses and atmospheres. TESS has so far discovered seventeen small planets around eleven nearby stars that are M dwarfs….more

Water On The Moon Confirmed, And There May Be Much More Than We Thought  NASA’s intriguing announcement last week that it would reveal an “exciting discovery about the Moon” led to a lot of speculation on what this big discovery might be. We can now all share in the excitement of the space agency: the Moon appears to have a lot of water, and this could make future exploration of our natural satellite much easier…more

Water on the Moon could sustain a lunar base Having dropped tantalising hints days ago about an “exciting new discovery about the Moon“, the US space agency has revealed conclusive evidence of water on our only natural satellite. This “unambiguous detection of molecular water” will boost Nasa’s hopes of establishing a lunar base. The aim is to sustain that base by tapping into the Moon’s natural resources…more
