As we all know Olympus Mons is the most extreme volcano in the solar system, which is located in the Tharsis volcanic region of Mars. Its height of 25 kilometres makes it nearly three times the height of Earth’s Mount Everest, which is about 8.9 km high.

WHAT IS A SOLAR STORM? LEARN ALL ABOUT SOLAR STORMS
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
MEASURING THE SPIN OF A BLACK HOLE
Astronomers are able to measure the masses of black holes in a relatively straightforward way: watching how matter moves in their vicinity (including other black holes), affected by the gravitational field.
SOME PROGRESS AT LAST! MARS INSIGHT’S MOLE IS NOW UNDERGROUND
After several assists from InSight Lander’s arm, the mole appears to be underground. It’s been a real challenge troubleshooting for NASA & DLR from millions of miles away. We still need to see if the mole can dig on its own. There was no way to predict the duracrust and what it meant for the Mole. The future is still uncertain.
COULD NEWLY DISCOVER SALTWATER PUDDLES OF MARS HAVE SUPPORTED LIFE?
An analysis of new rock samples taken from NASA’s Curiosity rover uncovered evidence of clay minerals on Mars, suggesting the presence of water from a large, ancient lake. While the presence of clay supports the notion Mars may have once had water, it doesn’t conclusively prove the planet harboured conditions for life.
SECRETS OF ASTEROID RYUGU
Ryugu’s interaction with the sun changes what we know about asteroid history. In February and July of 2019, the Hayabusa2 spacecraft briefly touched down on the surface of near-Earth asteroid Ryugu. The readings it took with various instruments at those times have given researchers insight into the physical and chemical properties of the 1-kilometer-wide asteroid. These findings could help expla
GEMINI GETS LUCKY AND TAKES A DEEP DIVE INTO JUPITER’S CLOUDS
Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. These images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. The Gemini images, when combined with the Hubble and Juno observations, reveal that lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The new observations also confirm that dark spots in the famous Great Red Spot are actually gaps in the cloud cover and not due to cloud colour variations.
TURBULENT SKIES OF NEARBY FAILED STAR SPOTTED BY THICK CLOUD BANDS
Scientists have spotted evidence of Jupiter-like stripes in the thick atmosphere of a nearby brown dwarf, a new study reports — and this evidence was gathered in a novel way.
WIND SPEED OF A BROWN DWARF MEASURED FOR THE FIRST TIME
For the first time ever, astronomers have measured wind speed on a brown dwarf, or “failed star,” an object heftier than a planet but not massive enough to host the fusion reactions that power stars.
A NEWFOUND BLACK HOLE IS THE CLOSEST ONE TO EARTH WE HAVE EVER FOUND
A newfound black hole may be the closest black hole to Earth, and you can spot its cosmic home in the night sky without a telescope.
NASA’s NEIL GEHRELS SWIFT OBSERVATORY TRACKS WATER LOSS FROM INTERSTELLAR COMET 2I/BORISOV
Astronomers using NASA’s Neil Gehrels Swift Observatory have tracked water loss from 2I/Borisov, the first known interstellar comet to visit our Solar System, as it approached and rounded the Sun. Their findings were published in the Astrophysical Journal Letters.
COULD A GIANT SPACE UMBRELLA HELP COOL DOWN OUR PLANET?
It’s a radical idea, and it just might just work. Reducing the amount of light reaching our planet could cool the Earth quickly, even with rising carbon dioxide levels. While the asteroid which helped wipe out the dinosaurs blocked out 90% of the Sun’s rays, we would need to divert just 2-4%, it’s believed, to take the Earth back to its pre-industrial climate.
ONLY ONE PERSON WAS EVER KILLED BY A METEORITE SINCE 1800, TERRIBLE LUCK I WOULD SAY
What are your chances of getting smacked and killed by a meteorite? One astronomer put the odds of death by space rock at 1 in 700,000 in a lifetime, while others say it’s more like 1 in 1,600,000.
New Kaleidoscopic Map Details the Geology of the Moon
This animation shows a rotating globe of the new Unified Geologic Map of the Moon with shaded topography from the Lunar Orbiter Laser Altimeter (LOLA). This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions. It will serve as a reference for lunar science and future human missions to the Moon. Credit: NASA/GSFC/USGS.
MIRROR-SYMMETRY VIOLATION IN BOUND NUCLEAR GROUND STATES
The breakthrough by the researchers revealed that a symmetry that exists within the core of atoms is not as fundamental as scientists have believed. The discovery sheds light on the forces at work within the nucleus of atoms, opening the door to a greater understanding of the universe.
