GEMINI GETS LUCKY AND TAKES A DEEP DIVE INTO JUPITER’S CLOUDS

Jupiter seen with Gemini’s Lucky

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.

WHAT IS FRACKING? FACTS ABOUT FRACKING

Hydraulic fracturing, Also Known As Fracking, is a Well stimulation technique in which rock is fractured by a pressurized liquid. The process involves the high-pressure injection of ‘fracking fluid’ (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures op

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.

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.

DO YOU KNOW HOW OUR BLOOD VESSELS HEAL THEMSELVES AND ANSWER TO THIS QUESTION HAS THE POTENTIAL TO SAVE MANY LIVES?

A four-week-old human embryo already has miles of blood vessels. By adulthood, we each have 60,000 miles of blood vessels inside our bodies – that’s more than twice the distance around the world. Those vessels keep blood flowing, supplying your tissues with oxygen and nutrients and keeping your organs, including the heart, healthy. In the … Read more

NOVEL PROTEIN PLAYS A KEY ROLE IN THE TRANSDUCTION OF MECHANICAL CUES TO BLOOD VESSELS

Cella and tissues are far from being mere static structures. They have the ability to sense and dynamically react to external cues to ensure that they adapt to the ever-changing outside environment. Now, researchers from the University of Tsukuba have identified a novel protein that plays a central role in the transduction of external mechanical … Read more
