![]() 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.

Some researchers expect that with the progressing climate change, dust storms will intensify as higher temperatures are likely to create more dust. 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. At the moment though, you're paying just to have the images and explanations delivered to your menu bar instead of viewing them on the official website.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. ![]() ![]() Perhaps is some more features were added in the future, the app might be worth the price. A $10 yearly subscription will guarantee an endless supply of images and explanations, but it does seem a bit excessive considering that both the images and descriptions are already freely available on NASA's website. While the app certainly seems interesting, and it appears to run without issues, it does come with a not-insignificant price tag. These images can be saved on your Mac and used as you see fit, but you also have the option of setting them as your wallpaper directly, straight from the app's interface. A new image is delivered to your menu bar every day, courtesy of NASA's Astronomy Picture of the Day API, which is available to the public. Of course, knowledge is only one thing the app provides. High-quality images that can be set as wallpapers Fortunately, this app keeps things simple, with a fairly concise description that explains everything in layman's terms.Īgain, you shouldn't exactly rely on this application to teach your children everything about space, but it can help get them interesting in the first place, and that applies to adults as well. If you don't have a background in astronomy, lengthy, complicated explanations probably won't grab your attention, even if you are interested in the subject. Educational app that supplies bite-sized lessons It runs in your menu bar and provides you with a new space image or photograph every day, along with a brief explanation from a professional. ![]() While NASA Picture of the Day can't do too much about all that, it should help regular people like you and me learn a little bit more about our Universe, in a fun and engaging way. Even a degree in astrophysics only guarantees you a minute amount of knowledge compared to what can still be learned about outer space. The Universe around our little planet is fascinating, possibly infinite, and almost completely unknown. ![]()
