![]() ![]() Planetary Mysteries by Richard Grossinger has rekindled my interest, to put it mildly. Either “they” would find us, or it would be quite a while before we could extend the search to other stars. But as one planetary probe after another turned up nothing but rocks or swirling, poisonous gases - no life and no evidence of any ancient civilizations, at least in our own solar system - I lost interest. Common sense suggests it (as well as every science fiction book I’ve read since I was twelve). The rotation of the image on the sky with respect to the north pole of the celestial sphere.I’ve never doubted there was life on other planets. The date and time the release content became public.Ī brief description of the methods used to convert telescope data into the color image being presented. The primary individuals and institutions responsible for the content. The camera filters that were used in the science observations. The date(s) that the telescope made its observations and the total exposure time. The science instrument used to produce the data. "PI" refers to the Principal Investigator. Science Team: The astronomers who planned the observations and analyzed the data.Proposal: A description of the observations, their scientific justification, and the links to the data available in the science archive.The physical size of the object or the apparent angle it subtends on the sky. Interstellar distances can also be measured in parsecs. ![]() Solar system are usually measured in Astronomical Units (AU). The physical distance from Earth to the astronomical object. One of 88 recognized regions of the celestial sphere in which the object appears. Right ascension – analogous to longitude – is one component of an object's position.ĭeclination – analogous to latitude – is one component of an object's position.

Additional image processing and analysis support from: K. These data are taken from HST proposal 10065 by J. The planet has a diameter of 4,222 miles (6,794 kilometers) at the equator. Shkuratov (Kharkov U.)ĭistance from the Sun: The semi-major axis of Mars' orbit about the sun is 1.52 Astronomical Units (A.U.) or 142 million miles (228 million km) Distance from the Earth: At the 2003 closest approach, Mars was approximately 35 million miles (56 million kilometers) from Earth. Wolff (SSI) Additional image processing and analysis support from: K. The orange streaks are indications of dust activity over the polar cap.Ĭredits NASA, J. During this season the Sun shines continuously on the southern polar ice cap, causing the cap to shrink in size. The pictures were taken during the middle of summer in the Southern Hemisphere. īoth images show most of the southern polar ice cap. The striking features in this portrait are Olympus Mons, the largest volcano in the solar system and Solis Lacus, an immense dark marking also known as the "Eye of Mars". 27 with Hubble's Wide Field and Planetary Camera 2. This photo was assembled from a series of exposures taken between 5:35 a.m. ![]() Mars is a mere 1,400 miles closer to Earth in this picture than in the one taken 11 hours earlier. The image at right was snapped within minutes of the red planet's close rendezvous with Earth, when the two planets were 34,647,420 miles (55,757,930 km) apart. The prominent Martian features in this photo are Syrtis Major, the "shark-fin" shape on the right and the Hellas impact basin, the circular feature near the center of the image. Hubble snapped this photo when Mars and Earth were 34,648,840 miles (55,760,220 km) apart. 26 with Hubble's Wide Field and Planetary Camera 2. The image at left was assembled from a series of exposures taken between 6:20 p.m. Mars completed nearly one half a rotation between the two observations. Hubble snapped these photos as the red planet was making its closest approach to Earth in almost 60,000 years. These two images, taken 11 hours apart with NASA's Hubble Space Telescope, reveal two nearly opposite sides of Mars.
