Iron and titanium in the atmosphere of an exoplanet

Exoplanets can orbit close to their host star. When the host star is much hotter than our sun, then the exoplanet becomes as hot as a star. The hottest ‘ultra-hot’ planet was discovered last year. A team has now discovered the presence of iron and titanium vapors in the atmosphere of this planet. This detection was made possible by the surface temperature of this planet, which reaches more than 4,000 degrees.

NASA launches probe to go deep into Sun's scorching atmosphere

NASA launches probe to go deep into Sun's scorching atmosphereThe craft will endure extreme heat while zooming through the solar corona to study the Sun’s outer atmosphere that gives rise to the solar winds. It is set to fly into the Sun’s corona within 3.8 million miles (6.1 million km) of the solar surface, seven times closer than any other spacecraft. The corona gives rise to the solar wind, a continuous flow of charged particles that permeates the solar system and can cause havoc with communications technology on Earth.

NASA spacecraft ready to launch through Sun's burning atmosphere

NASA spacecraft ready to launch through Sun's burning atmosphereThe first ever spacecraft to fly directly toward the Sun is poised to blast off Saturday, on a mission to plunge into our star’s sizzling atmosphere and unlock the mysteries of the center of the solar system. NASA’s car-sized, $1.5 billion Parker Solar Probe is scheduled to launch on a Delta IV Heavy rocket from Cape Canaveral, Florida during a 65-minute launch window that opens at 3:33 am (0733 GMT). “We are going to be in an area that is so exciting, where solar wind — we believe — will be accelerating,” said NASA planetary science division director Jim Green.

Atmosphere–soil carbon transfer as a function of soil depth

Atmosphere–soil carbon transfer as a function of soil depth

Atmosphere–soil carbon transfer as a function of soil depth, Published online: 11 July 2018; doi:10.1038/s41586-018-0328-3

This study of whole-soil carbon dynamics finds that, of the atmospheric carbon that is incorporated into the topmost metre of soil over 50 years, just 19 per cent reaches the subsoil, in a manner that depends on land use and aridity.

Hubble detects helium in the atmosphere of an exoplanet for the first time

Astronomers using the NASA/ESA Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the Solar System. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres.

China says Tiangong-1 space station to enter Earth's atmosphere on Monday

China says Tiangong-1 space station to enter Earth's atmosphere on MondayChina’s Tiangong-1 spacecraft will re-enter the Earth’s atmosphere at some point on Monday, the country’s space agency said in a statement. The Manned Space Agency did not specify a time when it expects the craft to enter the atmosphere in its statement on Sunday. South Korea’s National Space Situational Awareness Organization said on its website Sunday that the station is expected to re-enter the atmosphere sometime between 5:12 a.m. and 1:12 p.m. Seoul time (2012 GMT to 0412 GMT) on Monday.
