WMAP
The Wilkinson Microwave Anisotropy Probe (WMAP) was launched in 2001 and measured the temperature of the radiation left over from the Big Bang.
The craft can map out the fluctuations in the presumed cosmic microwave background radiation.
The data from WMAP revealed a better estimate for the age of the universe.
It confirmed that about 95 percent of the universe is composed of dark matter and dark energy.

NASA's 10 Greatest Science Missions
Pioneer 10 and Pioneer 11 were launched in 1972 and 1973. They were the first spacecraft to visit Jupiter and Saturn in a one-way voyage.
Pioneer 10 traveled through the solar system's asteroid belt between Mars and Jupiter.
A year-and-a-half after it's laun...
The photos of the Hubble Space Telescope is recognized around the world. It has radically changed science.
NASA developed a tool that could reveal starts, planets, nebulae, and galaxies in detail.
Spirit & Opportunity
In 2004, these twin Mars Exploration Rovers landed on opposite sides of the planet and explored it for more than five years.
Among the major finds is evidence that the surface of Mars once had liquid water.
NASA's Viking 1 was the first man-made object that soft-landed on Mars in July 1976.
The Viking 1 lander is also the longest-running Mars surface mission, and sent the first color pictures back from the surface of Mars,
The Spitzer Space Telescope observes the heavens through infrared light.
It takes stunning photos of galaxies, nebulae, and stars.
In 2005, Spitzer detected light from extrasolar planets.
Voyager 1 and Voyager 2 probes followed after the Pioneers.
They made many important discoveries about Jupiter and Saturn.
Discoveries include rings around Jupiter and volcanism on Jupiter's moon.
Voyager made the first flybys of Uranus, where it discovered ten new ...
The earth's atmosphere blocks out most X-rays and prevents astronomers from viewing the universe in X-ray light - a high-energy, short-wavelength light.
In 1999, the Chandra X-ray Observatory was sent up to space. It scans the skies in X-ray light and can see X-ray sources 100 times ...
Cassini-Huygens
NASA/ESA spacecraft was launched in 1997 and reached Saturn in 2004. Since then its been orbiting around the planet and taking photos of the planets' rings, moons, and weather.
The Huygens and Cassini probes separated. Huygens made a trip to the moon Titan and landed on solid ground in 200...
NASA's best space mission was the Apollo, taking humans along. The Apollo trips brought moonrocks home. The astronauts gathered data that helped us learn the likely age of the moon and what it's made of.

Jupiter is our fith planet from our Sun and is by far, the largest planet in the solar system - more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupite...

Mars has captivated people since we first saw the reddish hue object in the night sky. In the late 1800s, telescopes revealed a surface full of patterns and landforms thought to be a bustling Martian civilisation.
Now, we know there are no constructions on Mars....

The Fermi Paradox states that given the technological advancement and imperialistic desires of human beings who live in a fairly young planetary system, aliens from other highly advanced star systems should have visited earth already and even conquered the Milky Way galaxy if they desired.
