“THE CoRoT-7b super-Earth. The atmosphere is made of rocky vapours with a very low pressure (P ⩽ 1.5 Pa), no cloud can be sustained, and no thermalisation of the planet is expected. The dayside is very hot (2474 ± 71 K at the sub-stellar point) while the nightside is very cold (50–75 K). The sub-stellar point is as hot as the tungsten filament of an incandescent bulb, resulting in the melting and distillation of silicate rocks and the formation of a lava ocean.” https://lnkd.in/dDkzNen View in LinkedIn

JUPITER, SATURN AND VENUS. “In contrast to planets like the Earth, Jupiter or Saturn, Venus does not have an intrinsic magnetic field and thus its atmosphere is not protected against the incoming solar wind. However, solar UV radiation ionizes the upper atmosphere creating an ionosphere which in turn interacts with the solar wind ions and the magnetic field carried by the solar wind.” https://lnkd.in/dVhpP9H View in LinkedIn

MERCURY. “In contrast to the other terrestrial planets Mercury does not have an atmosphere, but it has a relatively weak magnetic field. The strong solar UV radiation leads to photo-chemical escape of ions from Mercury's surface. Also solar wind protons can penetrate through the magnetospheric cusps and sputter ions off the surface. Due to the absence of an ionosphere no significant energy can be stored in the magnetosphere of Mercury such that solar wind disturbances will lead to short time deformations of the magnetosphere.” https://lnkd.in/dVhpP9H View in LinkedIn

MARS. “In the absence of an intrinsic dipole magnetic field, Mars' O+ planetary ions are accelerated by the solar wind. Because of their large gyroradius, a population of these planetary ions can precipitate back into Mars' upper atmosphere with enough energy to eject neutrals into space via collision. This process, referred to as sputtering, may have been a dominant atmospheric loss process during earlier stages of our Sun. “ https://lnkd.in/djesTG5 View in LinkedIn

“VENUS is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick. Its clouds, which hide the surface from view, contain concentrated sulfuric acid — strong enough to dissolve most metals used to make spacecraft. The atmosphere is nearly as thick as liquid water because its surface pressure is extremely high — 93 times the pressure of Earth’s atmosphere.” https://lnkd.in/dAsAqH7 View in LinkedIn

SUPERMASSIVE BLACK HOLE COULD HAVE INFLUENCE EARLY EART EVOLUTION. “Traditionally, the Sun was thought to be the only astronomical source of light that affected life on Earth. But it is also possible that the black hole, SgrA played an important role in shaping the history of terrestrial life. A surprising realization of this sort is similar to figuring out that a stranger might have impacted your family history before you were born. If a link between SgrA* and terrestrial life can be established, then this supermassive black hole might trigger a second Nobel Prize.” (By Harvard Astronomy Chair, Abraham Loeb). https://lnkd.in/d3h297W View in LinkedIn

ALICE IN WONDERLAND. “If the SQM hypothesis is correct, then all observed pulsars may actually be SSs but not neutron stars, due to the contamination process by strange nuggets in the universe. SSs can exist in various forms, such as bare SSs or SSs with a normal baryonic crust.” (SQM = Strange-quark matter). (SS = strange stars). https://lnkd.in/ddQpCwa View in LinkedIn

NEUTRON STAR CORES. “Ordinary nuclei, made up of up and down quarks, may dissolve their boundaries and transit to an SQM phase (consisting of up, down, and strange quarks) if the nuclei experience high-enough pressure. Strange matter in bulk is stable. Even small chunks of strange matter with baryon number lower than 10(7), called "strangelets," can be stable due to surface tension.” (SQM = Strange-quark matter). https://lnkd.in/ddQpCwa View in LinkedIn
