Enveloping our planet and protecting us from the fury of the Sun is the magnetosphere, a key to helping Earth develop into a habitable planet.
Massive Cloud On Collision Course With Milky Way
In 1963, an astronomy student named Gail Smith working at an observatory in the Netherlands discovered something odd—a massive cloud of gas orbiting the Milky Way galaxy.
Smith's cloud contained enough gas to make 2 million stars the size of our sun, and it was moving through space at 700,000 mph.
30 million years from now, a massive cloud of gas will collide with the Milky Way. Astronomers are studying the incoming cloud and learning more about its origin.
Transient luminous events - a display of lights above the storm
Transient Luminous Events (TLEs) are flashes and glows that appear above storms and are results of activity occurring in and below those storms.
Researchers are working to better understand lightning and thunderstorms, how they form and develop over time, and why storms produce.
Mars Landing Sky Show
Since astronomers discovered that the stars in the sky are other suns, humanity has wondered if they are also orbited by planets and if those planets host alien life. Since the discovery of the first exoplanet only 25 years ago Hubble is among the many instruments trying to answer these questions. This new Hubblecast tells the story of what we know so far and what we can hope for in the future
