Earth’s gravity

After reading Newscientist’s article July eclipse is best chance to look for gravity anomaly by Phil McKenna, TBF has explored NASA’s archives to find out what our earth’s gravity looks like.
The total eclipse
The solar eclipse that will take place on Wednesday, July 22, 2009 will be a total eclipse of the Sun with a magnitude [...]

Saturn from space

NASA’s Cassini mission has been orbiting Saturn for five Earth years as of June 30, 2009. That’s about one sixth of a Saturnian year, enough time for the spacecraft to have observed seasonal changes in the planet, its moons and sunlight’s angle on the dramatic rings.
Saturn is the sixth planet from the Sun and the [...]

This mosaic combines 30 images—10 each of red, green and blue light—taken over the course of approximately two hours as Cassini panned its wide-angle camera across the entire planet and ring system on July 23, 2008, from a southerly elevation of 6 degrees.

Six moons complete this constructed panorama: Titan (5,150 kilometers, or 3,200 miles, across), Janus (179 kilometers, or 111 miles, across), Mimas (396 kilometers, or 246 miles, across), Pandora (81 kilometers, or 50 miles, across), Epimetheus (113 kilometers, or 70 miles, across) and Enceladus (504 kilometers, or 313 miles, across).

NASA's Cassini spacecraft captured these images at a distance of approximately 1.1 million kilometers (690,000 miles) from Saturn and at a sun-Saturn-spacecraft, or phase, angle of 20 degrees. Image scale is 70 kilometers (43.6 miles) per pixel.

High resolution Mars craters

Another visit to the High Resolution Imaging Science Experiment (HiRISE) of the University of Arizona, this time I have picked some craters and parts of craters from their Mars photos. First visit was about Phobos & Deimos, Mars moons .

Jupiter from space

Jupiter is the fifth planet from the Sun and the largest planet within the Solar System. It is two and a half times as massive as all of the other planets in our Solar System combined. Jupiter is classified as a gas giant, along with Saturn, Uranus and Neptune. Together, these four planets are sometimes [...]

This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA's Cassini spacecraft starting at 5:31 Universal time on December 29, 2000, as the spacecraft neared Jupiter during its flyby of the giant planet. It is the most detailed global color portrait of Jupiter ever produced; the smallest visible features are ~ 60 km (37 miles) across.

Mercury from space

Mercury is the closest planet to the Sun. Its diameter is 40% smaller than Earth and 40% larger than the Moon. It is even smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan.
In Roman mythology Mercury is the god of commerce, travel and thievery, the Roman counterpart of the Greek god Hermes, the messenger of [...]

Venus from space

Venus is the second-closest planet to the Sun, orbiting it every 224.7 Earth days. The planet is named after Venus, the Roman goddess of love. It is the brightest natural object in the night sky, except for the Moon.
Classified as a terrestrial planet, it is sometimes called Earth’s “sister planet”, because they are similar in [...]
