![]() "It was both a magical experience and a real struggle," Pesquet tweeted after the spacewalk. In this image, Pesquet can be seen waving into the camera after letting go of the rolled up 750 lbs (350 kg) iROSA solar array. During the 7 hour and 15 minute spacewalk, Pesquet and his colleague NASA astronaut Shane Kimbrough installed a new ISS Roll-Out Solar Array (iROSA) into its mounting bracket on the station’s backbone truss structure. Thursday, June 17, 2021: European Space Agency astronaut Thomas Pesquet attached to the tip of the robotic arm at the International Space Station during a spacewalk on Wednesday (June 16). Tereza Pultarova Worst drought spell in decades decimates Brazil’s coffee production ESA said in a statement the object will be among the targets of the NASA/ESA/CASA James Webb Space Telescope as astronomers seek to gain more insight into the processes powering extreme star formation. The image, taken by Hubble's Wide Field Camera 3, combines observations in eight different wavelengths ranging from infrared to ultraviolet. The merging galaxies are a part of the constellation Cetus (or Whale), the fourth largest constellation in the sky, which is located in the southern hemisphere close to Aquarius, Pisces and Taurus. The process is accompanied by a powerful inflow of gas that is triggering intense formation of new stars, hence the name "starburst". Astronomers use a single name for the pair of galaxies, IC 1623, as they are in the advanced stages of merging into one new "starburst" galaxy. Monday, June 21, 2021: Two galaxies colliding 275 million light years away from the sun have been captured by the Hubble Space Telescope in a new image revealing signs of intense star formation about to happen. Tereza Pultarova Oops, Ingenuity did it again. Compared to the previous estimate, they now believe the galaxy is farther away - 72 million light years compared to the previously estimated 42 million light years. Unlike in other galaxies, in the case NGC 1052-DF2, the visible stars seem to account for almost all of the galaxy's matter, which can be calculated by observing the dynamic processes inside the galaxy.Īstronomers focused on the brightness of red giant stars in the galaxy to calculate its distance from Earth. ![]() Recent observations carried out between December 2020 and March 2021 with Hubble's Advanced Camera for Surveys indicate the galaxy contains only about 0.25% of the amount of dark matter that the astronomers had expected. The galaxy has no visible center or structure and is so diffuse that more distant galaxies can be seen through it. The galaxy, discovered in 2018, is about as wide as the Milky Way but contains only about 0.5% of the amount of stars. Wednesday, June 23, 2021: The Hubble Space Telescope captured new images of a strange see-through galaxy named NGC 1052-DF2 that appears to lack dark matter.

The size of the plumes from the past two years is, however, quite exceptional, NASA said in a blog post. ![]() Every year, more than 180 million tons of Saharan dust get carried across the Atlantic by winds. Transport of dust from the African desert to the Americas takes place on a regular basis. At that time, sensors on NASA’s Earth-observing satellites measured record concentrations of dust in the atmosphere. The dust storm comes about a year after the largest cloud of Saharan dust in two decades hit the Caribbean Sea, dimming skies over several states of the U.S. Thursday, June 24, 2021: A massive plume of Saharan dust stirred up by strong winds in western Africa in early June is finding its way across the Atlantic towards Florida, as can be seen in this image captured by the NASA-NOAA Suomi NPP Satellite. ![]()
