Galileo Galilei (1564-1642) was part of a small group of astronomers who turned #telescopes toward the heavens.

Two #moons in the #Solar #System are larger than the planet #Mercury (though less massive): Ganymede and Titan, and seven are larger and more massive than the #dwarf #Planet #Pluto .

The 11-year #sunspot cycle is actually half of a longer, 22-year cycle of #SOLAR activity. Each time the sunspot count rises and falls, the magnetic field of the #Sun associated with sunspots reverses polarity.

#meteorshower are commonly called falling stars or shooting stars. If any part of the #meteoroid survives burning up and actually hits the #Earth, that remaining bit is then called a meteorite.⭐️ Journal of Astrobiology & Outreach

When two extremely dense dead #star cores collide, the #result is a kilonova. This is a #bright afterglow of the collision that's made of decaying #heavy elements. For a long time, #scientists thought precious #metals and heavy elements were ejected out of supernovae

The conditions during neutron #star mergers are so intense that some of the universe's heaviest and most precious elements, such as #gold, #Platinum and #silver , are forged by these collisions.

Observations from #NewHorizons are continuing to revolutionize our understanding of #solarsystem objects orbiting far from the sun. visit: bit.ly/3htzUai

Received an invitation from Dr Srinubabu Gedela garu, CEO-Pulsus Group, to attend the Tech Summit to be held in Vizag during Feb 2023. These type of technology summits and conferences are a pre-launch popularisation events for #G20India presidency. @Vizagtechsummit

Events like Vizag Tech Summit 2023 are one of their kind as pre-launch popularisation events for India’s G-20 presidency. More technological startups with Indianness are being encouraged. Thanks to Nirmala Sitharaman #vizagtechsummit #G20India #G20IndiaPresidency #globaltechsummit

The #responses of Earth’s and Mars’ thermospheric densities to quasi-periodic solar rotation variations in flux were ##measured contemporaneously by the MAVEN, GOES, and Swarm-C satellites visit: bit.ly/3YpZiyx

Important altitude dependencies in the sensitivities are found in the #Martianthermosphere, while the #terrestrialthermosphere is shown to exhibit only small (±5%) day/night and latitude variations in the response visit:bit.ly/3YpZiyx

The influence of fluids on fluid-driven #seismicity is generally well accepted but the temporal behaviour and the migration of #activatedphases Visit: bit.ly/3WGTgIB

The phenomenon ‘earthquake swarm’ is well known from numerous locations on Earth but its #mechanism and trigger process are still an #Enigma Visit:bit.ly/3WGTgIB

#Martiansnow comes in two varieties: water ice and carbon dioxide, or dry ice. Because Martian air is so thin and the temperatures so cold, #water-ice snow sublimates, or becomes a gas visit: bit.ly/3WGTgIB

Water and carbon dioxide can each form frost on #Mars, and both types of frost appear far more widely across the planet than snow does. The Viking landers saw #water frost when they studied Mars visit:bit.ly/3WGTgIB

Ice #nucleation is found to influence simulated cloud feedbacks not just over extratropical low clouds but over most regions and levels of the #troposphere visit:bit.ly/3WGTgIB

wavelength calibration using on-orbit observations, use the #backscatter measurements in a direct spectral fit of radiances, in combination with a nadir reference spectrum collected over a clean area, to determine #slant columns of HCHO visit:bit.ly/3WGTgIB

Meteor showers occur annually or at regular intervals as the Earth passes through the trail of dusty debris left by a comet. #Meteorshowers are usually named after a star or constellation that is close to where the #meteors appear in the sky visit:bit.ly/3WGTgIB

The #fireball was most likely caused by a small meteor, up to a few metres in diameter, traversing Earth’s atmosphere. It was one of only five impacts of greater than a thousand tonnes of #energy globally in the past year visit:bit.ly/3WGTgIB

Above 1,000 delegates from 25 countries such as the UK, USA, Europe and also from African countries would take part in it. European Business Technology Center (EBTC) would set up a center of excellence in Vizag #GlobalTechSummit
