Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy.

MIT scientists have uncovered a sprawling new galaxy cluster hiding in plain sight. The cluster, which sits a mere 2.4 billion light years from Earth, is made up of hundreds of individual galaxies and surrounds an extremely active supermassive black hole, or quasar.

In a study, a new HIV drug reduced viral replication and increased immune cells in individuals with advanced, drug-resistant HIV infection. Used in combination with existing HIV medications, the drug is a promising strategy for patients who have run out of effective treatment options, the researchers said.

NASA’s Opportunity rover has been silent since June 10, when a planet-encircling dust storm cut off solar power for the nearly-15-year-old rover. Now that scientists think the global dust storm is “decaying” — meaning more dust is falling out of the atmosphere than is being raised back into it — skies might soon clear enough for the solar-powered rover to recharge and attempt to “phone home.”

NASA’s Solar Dynamics Observatory (SDO) scientists used their computer models to generate a view of the Sun’s magnetic field on August 10, 2018. The bright active region right at the central area of the Sun clearly shows a concentration of field lines, as well as the small active region at the Sun’s right edge, but to a lesser extent. Magnetism drives the dynamic activity near the Sun’s surface.

Scientists report the discovery of a structurally ‘inside-out’ planetary nebula — the ionized material that surrounds a white dwarf. The research team believes this inverted ionization structure of the nebula is resulted from the central star undergoing a ‘born-again’ event, ejecting material from its surface and creating a shock that excites the nebular material.

Researchers discovered the presence of iron and titanium vapors in the atmosphere of exoplanet KELT-9b. The detection of these heavy metals was made possible by the surface temperature of this planet, which reaches more than 4000 degrees.
