Research during the latter half of this century has led to the development of a generally accepted concept of how stars and planetary systems form. The concept suggests that objects similar in mass and composition to Earth may exist in many, perhaps most, planetary systems. Detection of such planets is a key outcome of the search for planetary systems in general.

We must conduct an extensive census of mature systems to determine the orbital characteristics and gross physical properties of extrasolar planets. In particular, we need to make a complete inventory of all nearby stars to find all Jovian-mass planets, and as many Neptune-like (ice-rock) planets as possible. This will require radial velocity precision of 1 m/s or better, astrometric precision of 50 microarcseconds, and the ability to image planets a few tenths of an arcsecond from a star.

Yes. One of the most active areas of astronomy research right now involves the search for what are called Extrasolar Planets; planets that are in orbit around other stars. As of this writing, over a hundred have been found at the rate of one or two every month, sometimes more. It is likely that all most or all single stars and maybe a few multiple star systems have other stuff in orbit around them. This stuff could include any of the kinds of things that orbit our Sun.

State definitions vary; however, in general, life-sustaining medical treatment is anything mechanical or artificial that sustains, restores, or substitutes for a vital body function and that would prolong the dying process for a terminally ill patient.

Life as we know it can only exist with the presence of liquid water, organic compounds and a source of energy (such as sunlight). So far, scientists have found those elements in the right combinations only on Earth. But certain locations in our solar system hold at least pieces of the puzzle of life - Mars, comets and, possibly, Jupiter's moon Europa. Mars is the most likely location for life. Learn more >>

I've been to the moon, and when I described another location I had been to, someone said it was Mars (dome shaped buildings and a dark, shadowy atmosphere--like inside Mars). The life you see there is not physical, but astral (the life on Mars may have been physical, but not detected by our current technology. When I went to the moon, there was a structure there that was no longer inhabited, but when it was, it was by humans (mainly men). It appeared to be some sort of compound.

The JWST will be able to detect the likely presence of planetary systems around nearby stars from their infrared radiation. It may even be able to see directly the reflected light of large planets - the size of Jupiter - orbiting around nearby stars. It will also be possible to see very young planets in formation, while they are still hot. JWST will also detect planets that transit across their parent star.

Photographs of deep-sky objects, the moon and planets can be taken with conventional film cameras, CCD devices/digital cameras, and even video camcorders. Photography can be done without a telescope, with the camera "piggybacked" onto the telescope (i.e. telescope is used to guide the camera) or with the telescope as the camera's lens (prime focus photography).

When we ask about life in the universe, we have one point of reference: terrestrial life. Terrestrial life is entirely DNA based. But, when we search for life beyond Earth, we do not necessarily go looking for DNA-based life. We look for things that exhibit the common features of our life; that is, a self-organized, catalytic system capable of replication and evolution.

Our solar system officially has nine planets and one star: the Sun. In order from the Sun out, the planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the "Kuiper Belt" -- a collection of icy bodies located beyond Neptune-- should be called planets. Pluto itself belongs to the Kuiper Belt.

The distance is determined by the apparent magnitude range of 9th to 15th for the stars that Kepler will observe, the size of the star which determines the absolute magnitude of the various stellar types being observed and the size of the planet being detected. The detection threshold of Kepler is based on observing four transits of a 1.0 diameter Earth-size planet orbiting a 12th magnitude solar-like star. Since the Sun has an absolute magnitude of 4.

A little less than 1% of the stable sunlike stars in the solar neighborhood have giant inner planets orbiting them. This statistic is the result primarily of the survey done by the radial velocity method of detecting extrasolar planets.

In general, the answer is no. The only celestial object besides the Sun which is normally visible during the day with the unaided eye is the Moon, and even that is easy to overlook. But for several months each year, the next brightest object, Venus, is dazzling enough to be seen with the unaided eye in broad daylight. However, actually seeing Venus this way means waiting for the right time and knowing exactly where to look.

They don't. See the referenced question in the tarot section. An astrology chart is like a navigation chart of a river or body of water. It tells you about the currents and conditions, but once you know what is influencing your course, it is up to you to take charge of your own destiny.

Stars are stationary and are numerous. Planets are moving stars and are only 12 in number viz. Sun, Moon, Mars, Mercury, Venus, Jupiter, Saturn, Pluto, Neptune and Uranus. Rahu and Ketu, shown in any horoscope are called the shadow planets. Their effect is identified but not their presence.

I would love to see a feature that showed day/night in realtime say taken from the USNO atomic clock. Perhaps a setting where you could follow the terminator and such.

The stars are simply too far away. Our best rockets travel at about 10 miles per second. Even to reach the nearest other star system, Alpha Centauri, at about 4.2 light-years’ distance, would take such a rocket 60,000 years. There are about a thousand stars like the Sun within 100 light-years of us. To investigate them all with spacecraft would take millions of years and vast amounts of money.

Planets come in different sizes, compositions and colors. The four planets closer to the Sun are called "rocky" planets. They are small in size and similar to Earth in composition. They have no rings and only two of them (Earth and Mars) have moons. The four outer planets, also called "gas giants," are much larger than the rocky planets. They all have rings and have many moons.

Every picture of a spiral galaxy including our own, depicts a very bright, spherical center...I assume a dense cluster of stars. We can see this bright center in distant galaxies, and I've always wondered, why we don't see the bright center of our own.

A sustaining membership is a great way to support VPR. A sustaining member agrees to make a monthly contribution to VPR of $10 or more on an ongoing basis via a credit card or bank account. Your gifts will be automatically transferred around the 15th of each month—no more renewal notices! Sustaining memberships provide VPR with a steady, reliable source of income that we can count on month after month.

Yes, there is life on other planets. They have their own gods who created the whole Universe just for them, just like you do here. I could provide a variety of glib one-liners. Instead, since I am rather fond of this question, I'll flesh the answer out a bit. The Creator seems to define Evil as any knowledge that doesn't originate from His Word.

Life-sustaining treatment is treatment that, based on reasonable medical judgment, sustains the life of a patient and without which the patient will die. It means includes both medications and artificial life support (mechanical breathing machines, kidney dialysis treatment, and artificial nutrition and hydration).

The symbols that we use for each planet come from the Celtic people who once lived in the British Isles as well as other places in Europe.

Stars! is an Advanced Interstellar Strategy Game and a member of 4x genre (eXplore, eXpand, eXploit, eXterminate) of PC games. It was written by Jeff Johnson and Jeff McBride with help from Jeffrey Krauss (collectively known as the Jeffs). It was originally written in 1995 and is still as fun to play now as it ever was.

It depends on which planet you're looking at. The most distant planets Uranus & Neptune are very faint - even in binoculars they look very star-like. Pluto requires a telescope. However, for the closer planets (Mercury, Venus, Mars, Jupiter and Saturn), things are easier. They are very bright, and easily visible by the unaided eye. The shape of Mars' orbit means that over a period of months it can vary in brightness quite noticeably - but even so, you can't mistake the orange-red colour.

There are several worlds available in World Wind. The Earth, Moon, Mars, Venus and Jupiter are included and more can be added through add-ons. edit] I would love to see a feature that showed day/night in realtime say taken from the USNO atomic clock.
