Between April 28 and 29, 2015 a solar flare produced a filament that spread to a really huge distance. The result is that the images of the space probe SOHO (Solar and Heliospheric Observatory) that captured the filament, to include it cover a wide area of 45 million kilometers (about 30 million miles).
An article published in the journal “Nature” describes a research carried out using NASA’s space telescope NuSTAR (Nuclear Spectroscopic Telescope Array) to examine the central area of the Milky Way. A mysterious glow shows an amount of X-rays higher than expected and could be caused by emissions from zombies stars.
NASA has confirmed that a few hours ago the Messenger (MErcury Surface, Space ENvironment, GEochemistry and Ranging) space probe ended its mission by crashing on the surface of the planet Mercury. Messenger ran out of fuel and some maneuvers were recently programmed to prolong its life of a few more days. Eventually, even the helium normally used to pressurize the propellant was released in a jet that gave the probe one last push. It was a very successful mission that allowed us to discover many things about Mercury.
On April 24, 1990, the Space Shuttle Discovery was launched in its STS-31 mission. In its cargo bay it carried a really special payload, the Hubble Space Telescope. The day after it was deployed in its orbit, just over 550 km (about 342 miles) altitude. On June 25, Hubble sent its first images, which revealed a flaw in its primary mirror that reduced its usefulness. The first of a series of service missions turned what had threatened to turn into a terrible failure into a symbol for science and technology that goes far beyond astronomy.
NASA has announced the creation of the NExSS (Nexus for Exoplanet System Science), coalition, an initiative dedicated to the search for life on planets outside the solar system. It puts together different disciplines because this research goes beyond just astronomy: for example, it’s of interest to planetary and climate science researchers.
