The Sun was born about 4.6 billion years ago from the gravitational collapse of a vast cloud of gas and dust. Material in the center of the cloud was squeezed so tightly that it became hot enough to ignite nuclear fusion.

Solar eruptions can be received with a shortwave radio near 20 MHz and often turn on rapidly and decay slowly. These bursts can be quite strong and often last for tens of seconds. You will hear the weak galactic background noise for several seconds, followed by a Solar radio noise burst.

Coronal Mass Ejections (CME's) from the Sun can expel particles equivalent to Earth's mass in a few hours. These events can trigger communication outages on Earth and lead to the aurora borealis.

Prominences are relatively cool clouds of gas suspended above the Sun and controlled by magnetic forces. NASA's STEREO spacecraft observed this visually stunning prominence eruption of ionized helium at about 60,000 degrees.

Mercury's surface closely resembles the Moon's. It's covered by impact craters, ancient lava flows, and quake fault lines. Mile-high cliffs stretch for hundreds of miles across the planet's surface.


NASA currently has a mission to Mercury. Keep up with all the updates here!

Did you know? Mercury's nighttime temperature is -300 degrees F and its daytime temperature is over 700 degrees F? This 1000 degree temperature swing between night and day is the largest in the solar system!

Cloud-covered Venus is the second planet from the Sun, and passes closer to Earth than any other planet. Even so, Venus remained shrouded in mystery until the Space Age because the clouds hide its surface from view.

(Earth's) Moon

The regular daily and monthly rhythms of Earth's only natural satellite, the Moon, have guided timekeepers for thousands of years. Its influence on Earth's cycles, notably tides, has also been charted by many cultures in many ages.

Mars inspires speculation like no other world in the solar system. Generations of Earth-bound dreamers have pondered its fiery glow and considered the possibility of life on the "Red Planet." Author H.G. Wells wrote of an attack by invading Martians, and Orson Welles scared unsuspecting Americans by bringing the story to radio.

Weather systems on Earth blow themselves out in a few days or weeks. On the solar system's giant planets, though, weather systems can last for decades. The record holder is Jupiter's Great Red Spot, which was first observed no later than 1830 -- and perhaps a good bit earlier. This oval storm system is wide enough to swallow two Earths, and the winds at its perimeter blow several times faster than the strongest hurricane ever recorded on Earth.

In 1955, Jupiter was discovered to be a strong source of radio emissions. Jovian radio emissions however were routinely converted into audio signals. Listening to Jupiter along with visually presenting these data can be a means of identifying the different types of Jovian radio bursts, distinguishing Jupiter from background noise and providing information about Jupiter's magnetic environment. Here are S-bursts caused when Io sweeps through Jupiter's magnetosphere.

The planet Saturn is a delicate giant. Although it is the second largest planet in the solar system, it's the least dense -- less dense than water. Chemical compounds in its upper atmosphere color its cloud bands in subtle shades of ivory, yellow, and tan. And broad, lacy rings encircle Saturn, making it the most beautiful planet in the solar system.

With ice geyers, Saturn's icy moon Enceladus is very interesting. Start an interactive here.


Liquid methane lakes, rocks made of ice water, and a balmy surface temperature of -290 degrees F, Saturn's moon Titan is quite bizzare. Launch your Titan explorer here.


Saturn is a source of intense radio emissions, which have been monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of Saturn's radio emissions.

To the eye alone, Uranus is a dull planet. It looks like a featureless blue-green ball, with few of the dynamic cloud patterns that decorate Jupiter and Saturn. Yet Uranus may have the most interesting history of any planet in the solar system: A collision soon after its birth may have knocked the planet sideways.

Neptune might be called the mathematicians' planet. German astronomer Johann Galle discovered it on September 23, 1846. The discovery was made possible, though, by the calculations of mathematicians Urbain Leverrier of France and John Couch Adams of England.

After 76 years of glory, the small ball of rock and ice known as Pluto was relegated to the solar system backwaters in 2006 when astronomers dropped it from the list of planets. Instead, it's simply the most famous member of the Kuiper Belt, a broad doughnut-shaped ring of objects that extends outward from just inside the orbit of Neptune, the most distant planet.


New Horizons flew passed Pluto in July 2015. The probe is currently relaying its Pluto data back to Earth.

Asteroids and NEO's

Best images of Ceres (left) and Vesta (right)

The asteroid belt between Mars and Jupiter is like the solar system's cluttered old attic. The dusty, forgotten objects there are relics from a time long ago, each asteroid with its own story to tell about the solar system's beginnings.To answer these questions, NASA launched a robotic probe named Dawn. Its mission: Fly to two giant asteroids, Ceres and Vesta, and explore them up close for the first time.


Near Earth Objects (NEOs) present a danger to Earth.

We're eagerly awaiting the arrival of the DAWN spacecraft at Ceres in Febuary 2015.

Latest DAWN mission status

Did you know? Ceres was considered a planet when discovered in 1801. Only after several other "planets" were discovered in nearly the same orbit the term asteroid was invented.


With the possible exception of Saturn's rings, comets are the most beautiful objects in the solar system. Their lacy tails can spread across millions of miles, giving them an ethereal quality that nothing else can match.


NASA has launched and conducted serval great comet missions, check these out...
