Nasa picture of the day for tablets1/9/2024 Perhaps the most conspicuous golf course appears in the lower left of each image. Meanwhile, the occasional park or meandering golf course appears green-brown. In these images, buildings and paved areas appear in shades of gray or beige, the clearest example being the McCarran International Airport near the bottom center of each image. In subsequent images, development spreads southward, and by 2004, the entire image shows cityscape, including Interstate 215 passing through southwestern portion of the city. By 1989, however, development filled the upper left corner-a residential area, complete with curving roads and semicircle streets. Here, the land on the city’s outskirts appears in shades of beige and tan, with just a hint of the street grid to come. ![]() Undeveloped land appears along the left edges of the top two images. These images of the western portion of the Las Vegas metropolitan area show the city’s steady spread into the adjacent desert landscape. The Thematic Mapper captured these true-color, photo-like images on (top to bottom) OctoJJand January 12, 2009. Las Vegas, Nevada, provides an example of the sensor’s ability to monitor change over time. With a resolution of roughly 30 meters (100 feet) per image pixel, Landsat 5’s Thematic Mapper does not detect objects as small as individual houses or trees, but the sensor can detect land use changes, including forest clearing, replanting, and urbanization, over a wide area. Although Landsat 5 needed the occasional software fix to continue functioning, by March 2009, it had provided images of our planet for a quarter of century. Originally intended to last just three years, the satellite exceeded its life expectancy by 22. Ultimately, though, we have a long time before we should have to worry about the Sun erupting with enough power to destroy the Earth.On March 1, 2009, NASA’s Landsat 5 satellite turned 25. When a solar flare hits the Earth, the energy from the flare can cause issues with satellites, GPS systems, and even high-altitude communication systems. Chief among these side effects is the radio blackouts that I mentioned previously. While the energy from these events can’t penetrate Earth’s atmosphere, they can create some unwanted side effects. ![]() This image of a solar flare might be breathtaking, but solar flares can be scary events. What happens when a solar flare hits Earth? The Earth’s magnetic field keeps energy from solar flares from entering the planet’s atmosphere. At the time that NASA captured the image of this solar flare, the Space Weather Prediction Center noted a possible strong radio blackout. As such, it is always worth keeping an eye on them when they happen. X-class solar flares are the most intense flares that the Sun creates. Where the last X-class flare was classified as an X2.2, this new flare was only an X1.1. In fact, at the end of April, the Sun blasted out the most powerful solar flare in the last five years. ![]() This flare follows a few others which have happened this week. It’s all part of the space agency’s attempts to learn more about our Sun, and to prepare should any of these solar flares erupt towards Earth. The observatory constantly watches the Sun for events like this. The space agency’s Solar Dynamics Observatory captured the image of the solar flare. PWJUI395Cc- NASA Sun & Space May 3, 2022 ![]() NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X-class. The Sun emitted a strong solar flare on May 3, 2022, peaking at 9:25 a.m.
