June 20, 2008 Ashlynn (age 16, Spain) Is there any other planets in our galaxy except the ones we already know about? Could there be a possibility that one of the unknown planets have a creatures living on it like Earth has humans? Are we just as big of a mystery to them as they are to us? What galaxy DO we live in? We live in the Milky Way galaxy (Vía Láctea, in Spanish). Other planets-like objects have been found, but so far there is no indication of extraterrestrial life.

April 28, 2008 janie (age 13, TN) How do we know that life on other planets need water, oxygen, and shelter if the only life we know of is on earth? We don't know! and we keep looking for these conditions because we know for sure that they could harbor life.

March 14, 2008 bharati (age 12, india) is there is life on any other planet except earth No as far as we know, but we keep looking!!

January 16, 2008 Ben (age 11, Burlington ON) What variables do scientists consider to figure out the odds of life being able to exist on a planet, besides the fact that life needs water and minerals and heat. Scientists look for space bodies that fulfill what is known as the "Goldilocks Theory", our web page of the same name will give you general information on this issue.

January 15, 2008 Jacob (age 10, United kindom) Is there life on other planets ? So far, the efforts to find extraterrestrial life have not been successful.

January 7, 2008 Caitlin (age 10,TX,USA) Do creatures realy live in space? Like aleins, monsters,ect.? So far, the efforts to find extraterrestrial life have not been successful.

December 19, 2007 dibyajyoti (age 19, orissa, india) is there any existance of life in our universe?
if not then what's about the ufo
So far, the efforts to find extraterrestrial life have not been successful.

September 12, 2007 karabo (age 13, south africa) is it true that aliens once came around south africa or do aliens exists? Scientis are, and have been for a long time, looking for extraterrestrial life. So far there is no proof of life outside our planet.

September 12, 2007 Aheli (age 12, India) Do Aliens really exist? Few days ago I read in a book some of the real incidence of an Alien. After reading it I was totally confused and excited. Scientis are, and have been for a long time, ooking for extraterrestrial life. So far there is no proof of life outside our planet.

August 21, 2007 Anmol (age 12, orissa, india) Are any living objects living in other planet? In our planet, life has been found under very harsh conditions, like around hydrothermal vents or vent chimneys at the bottom of the oceans. So far, life has not been found outside our planet, but scientists keep looiking!

July 20, 2007 radwa (age 15, egypt) are there any aliens in the space live on other planets? So far there have been no discovery of extraterrestrial life, but we keep looking!

July 20, 2007 monica (age 13, india) is there any sign of life in other planets or galxies ? So far there have been no discovery of extraterrestrial life, but we keep looking!

July 2, 2007 diego (age 11, marshall,tx) is their life on other planets So far, the efforts to find extraterrestrial life have not been successful.

January 28, 2003 Can bacteria live on Mars? At present, scientists are pretty sure that there is no life on Mars, and this includes bacteria. A few years ago a few scientists thought they had found evidence that bacteria used to live on Mars, but since then their evidence has been shown to be faulty (that is, scientists don't think that what they found was really evidence at all).
So although no one really knows for sure because we haven't done a lot to explore Mars (especially below the surface), scientists generally agree that in the cold temperatures on Mars (and without water), there is no life there. If life was found on Mars, it would have to be able to survive these extreme conditions.

September 23, 2002 Luisa (age 13, Bogota, Colombia) I have heared a theory that says that we are some kind alien experiment, is that true? why? I doubt that it's true, but no one knows for sure if there is life outside our solar system. A similar idea was proposed jokingly by Douglas Adams in the book "The Hitchhiker's Guide to the Galaxy".

September 23, 2002 Denis (age 20, India) Let's say a planet is 50,000 light years away and life began on that planet 40,000 years ago and now there is a thriving population there. When we look at that planet how will we know that there is life there if we are looking at the planet as it was 50,000 years before? Your question is a good one, and the answer is that we wouldn't know that there is life there. This is one of the reasons that many people believe the search for extraterrestrial life must go on despite the fact that we don't have any evidence yet that such life exists. We might just have to wait and see!

August 30, 2002 Caroline (age 15, UK) What things are scientists doing (or have done in the past) in the search for life elesewhere in the universe? The SETI program has been the most dominant program looking for life elsewhere in the universe. They aim to explore, understand and explain the origin, nature, prevalence and distribution of life in the universe. You can even participate in the SETI@home experience!

June 8, 2000 Roni (age 15, Israel) Hello, if UFOS are real, Do they travel to our world in speed of light?? Because if they are real, they come to us from a very far place!
Well, there's no way to know, since we haven't had a chance to talk to any! According to our laws of physics, it is impossible for anything with mass to travel at the speed of light.
However, they could travel at a speed very close to the speed of light. Maybe if you meet one some day, you can ask them how they do it!

July 19, 1999 Rebecca (age 23, Utah) What types of stars would life on other planets be associated with? If we assume that life on "other planets" evolved the same way that it did on the Earth, one must think that the stars close to those planets must be similar to the stars close to Earth. The most important star, the sun, is critical to the development of life. A planet must be close enough to its sun to trap some of its heat but not too close so that it burns up. For life to develop on another planet, it must have a star similar to our sun to provide heat and energy.
A good web site to look at is at NASA.

May 26, 1999 Carla (age 13, New York, USA) Can any life, even single celled, live on Mercury? Probably not. The temperatures on Mercury can reach 800 degrees F, hot enough to melt lead! Any living cell would be fried to a crisp rather quickly. Water hasn't been found on the planet, something that is necessary to sustain life. If we ever develop the technology to protect ourselves and provide the essentials for life, maybe one day we can live on Mercury.

June 22, 1998 Mr. Curry's class (Virginia, USA) If there was intelligent life on other planets, would it look like us or something weird? Well, I would think they would look much different than us. Even people who were born and raised in different countries here on Earth look different. So a being who grew up in a totally different environment on a totally different planet, would likely look much different. I imagine they would look strange to us at first, but I bet that we'd get used to them.

January 27, 1998 Erica (age 11, Alabama, USA) Have you or any scientist found an alien body before? I checked with all of the scientists sitting around the lab here, and nope, they haven't found any!

November 26, 1997 Sarah (age 12, Colorado, USA) Have you ever received any messages from or about other people or things on other planets? Do you think we are alone, is there any proof? None of us here at Windows to the Universe has ever received any messages from anyone from another planet! But to learn more about the possibility of life elsewhere in the universe, check out question #2 under "Alive and Living" and the corresponding link to our page about the Martian meteorite, ALH 84001.
