The Sun Isn't Yellow Or Orange; It's White
The sun's true color is almost pure white; it only appears to be amber near the horizon.LEARN MORE
Scientists will investigate how the corona reaches blistering temperatures, how the solar wind gets its speed and how space weather affects Earth.
NASA's Parker Solar Probe will "touch" the sun — sort of.
The surface of the sun is called the photosphere; that's the bright part that shines with visible light. It's so hot and energetic that anything that gets too close tends to get vaporized or at least much crispier.
So, the solar probe will fly through the corona, the outermost layer of the sun's atmosphere. It will use gravity assists at Venus to orbit closer to the sun than any other spacecraft — about 4 million miles from the surface.
There's still a lot we don't know about our star and its effects on our solar system. The Parker probe will study the plasma and the magnetic fields near the sun and could answer long-standing questions about the star's behavior.
"Why is the corona hotter than the surface of the sun? That defies the laws of nature," said Nicola Fox, a project scientist with the Johns Hopkins University Applied Physics Laboratory. "Why in this region does the solar atmosphere suddenly get so energized that it escapes from the pull of the sun and bathes all of the planets?"
Researchers hope their findings will help us get better at forecasting potentially dangerous space weather. Solar outbursts can damage our satellites and power grids, so the more warning we have, the better.
A full annular solar eclipse will cut across the state of Texas on Oct. 14, which could cause a dip in the state's solar energy production.
If you're not able to get to a place where you can see this eclipse, the next total solar eclipse is April 8, 2024.
NASA astronaut Frank Rubio will see his family in person for the first time in more than a year, after his unexpectedly lengthy time in space ended.
What factors have compelled millions of Venezuelans to leave their homeland and seek refugee status in Latin America, the Caribbean, and the U.S.?
Republican lawmakers met early in the morning on Saturday with just hours to go before a midnight deadline to fund government operations.
House passage came after Speaker Kevin McCarthy dropped plans for steep spending cuts and relied on Democratic help.
