The temperature of Chamber A at NASA’s Johnson Space Center in Houston is steadily dropping, creating a frigid environment for NASA’s James Webb Space Telescope that is in stark contrast to the heat of the city.
Images of Jupiter’s Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval.
High up in the clear blue noontime sky, the sun appears to be much the same day-in, day-out, year after year.
But astronomers have long known that this is not true. The sun does change. Properly-filtered telescopes reveal a fiery disk often speckled with dark sunspots. Sunspots are strongly magnetized, and they crackle with solar flares—magnetic explosions that illuminate Earth with flashes of X-rays and extreme ultraviolet radiation.

Roman Statesman Marcus Tullius Cicero said, “If you have a garden and a library, you have everything you need.”

With temperatures around the world climbing, melt waters from the continental ice sheets of Greenland and Antarctica are raising sea levels. Those ice sheets are melting from both above and below. Much of the ice lost from ice sheets comes from a process called calving where ice erodes, breaks off, and flows rapidly into the ocean. A large volume of ice is also lost from ice sheets melting on their surfaces.
For the first time in 99 years, a total solar eclipse will cross the entire nation on Monday, August 21, 2017. Over the course of 100 minutes, 14 states across the United States will experience over two minutes of darkness in the middle of the day.
