NASA closely measured a shockwave from Sun for first time
Gigantic interplanetary shockwaves reverberate across our Solar System, originating from the Sun and the bursts of charged particles or solar winds escaping it.
One of Sun's biggest mysteries just solved
The waxing and waning of sunspots form part of our Sun's natural cycle, but it's a phenomenon astronomers still don't fully understand. Now, new research has revealed that particular "terminator" events are what brings sunspot cycles to an end, and it means we could get better at predicting them.
Sun, hot temperatures can take toll on mind, body
Keeping your cool means staying calm through tense, angry, or chaotic situations, and it’s one key to a healthy heart. But what if it’s 90°F?
NASA’s Voyager 2 reaches interstellar space
NASA's Voyager 2 probe has left the protective bubble around the Sun and is flying through interstellar space, becoming the second human-made object to travel so far, the US space agency says.
NASA launches historic mission to 'touch Sun'
NASA on Sunday launched a $1.5 billion spacecraft toward the Sun on a historic mission to protect the Earth by unveiling the mysteries of dangerous solar storms.
NASA's red-hot voyage to Sun will bring us closer than ever to our star
A red-hot voyage to the Sun is going to bring us closer to our star than ever before.
Solar storm warning: Giant tears in Sun’s corona trigger communication blackouts
The disastrous effects solar storms have on the planet were last seen in September 2017, at the height of the Atlantic hurricane season.
Meteorite's blue crystals offer insights into young sun's chemistry
Scientists have found minerals old enough to shed light on the composition and behavior of the Sun shortly after its birth, 4.6 billion years ago.
The Sun shrinks a teensy bit when it’s feeling active
How big is the Sun? Well, that depends on when you’re measuring.
What will Sun look like after it dies?
All stars die, and eventually — in about five billion years — our Sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.
Solar Dynamics Observatory serves up the Sun, three ways
How the Sun looks through the lens of a telescope depends on which frequency is being observed. NASA's Solar Dynamics Observatory is capable of imaging the Sun in a wide range of frequencies.
Scientists close to developing nuclear fusion star with same energy as Sun to power homes
The UK Atomic Energy Authority (UKAEA) is trying to secure a £1 billion contract to develop technology for use in the first nuclear fusion power plants.
Facts about Uranus
Uranus is the seventh planet from the Sun and the first to be discovered by scientists. Although Uranus is visible to the naked eye, it was long mistaken as a star because of the planet's dimness and slow orbit. The planet is also notable for its dramatic tilt, which causes its axis to point nearly directly at the Sun.
Will the Sun put the brakes on global warming?
The Sun is like a teenager that cycles through mood swings — from dramatic to chill and back again — roughly every eleven years.
Cassini, Voyager missions suggest new picture of Sun's interaction with galaxy
New data from NASA's Cassini mission, combined with measurements from the two Voyager spacecraft and NASA's Interstellar Boundary Explorer, or IBEX, suggests that our Sun and planets are surrounded by a giant, rounded system of magnetic field from the Sun — calling into question the alternate view of the solar magnetic fields trailing behind the Sun in the shape of a long comet tail.
