The schedule for the International Space Station crew rotation has been officially changed. Following the mishap with the Russian spacecraft Progress M-27M it was decided to postpone the launch of the next three members so the three ones of the Expedition 42/43 – Samantha Cristoforetti, Terry Virts and Anton Shkaplerov – will remain on the Station at least until the beginning of June.
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).
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.
ESA’s space probe Rosetta identified new jets of gas and dust emerge from the comet 67P/Churyumov-Gerasimenko. The images were taken using the OSIRIS camera on March 12, 2015 and were presented last week during EGU2015 (European Geosciences Union General Assembly 2015) in Vienna. The activity on the comet keeps on increasing but it took some luck to detect new jets.
When astronomers started studying a map of the cosmic microwave background radiation (CMB or CMBR), the residue of the earliest stages of the universe, they found what was called the Cold Spot. That’s a huge area colder than expected which could be the largest single cosmic structure never identified. According to an international team of scientists consists of a cosmic supervoid which about 1.8 billion light years across.
