Extrasolar planets — Earth-like planets

Extrasolar planets is one of the most interesting astronomical research topics. It can help us answer questions such as whether there are aliens, or is it possible for us to find another “Earth” to live on. An extrasolar planet is defined as a planet that is outside of solar system. The history of extrasolar planet … Continue reading Extrasolar planets — Earth-like planets Continue reading Continue reading

Exoplanets 101: Does the earth have a twin?

Potential Habitable Planets An extrasolar planet is a planet that orbits a star that’s not our sun. Even though these planets can be recognized, and their sizes measured, they are light years away so it would take astronomers thousands of years to reach these extrasolar planets. To detect these planets, scientists use either one of … Continue reading Exoplanets 101: Does the earth have a twin? Continue reading Continue reading

Extrasolar Planets: A Search to Span Solar Systems

Recently, I have started work as an undergraduate research assistant in the Physics and Astronomy department at my university. The project I was assigned to is of a stellar nature; we are attempting to find evidence of extrasolar planets, or planets around other stars. Though we haven’t found any planets yet, I keep thinking about … Continue reading Extrasolar Planets: A Search to Span Solar Systems Continue reading Continue reading

Some Planets Are Just So Extra… (Extrasolar, That Is)

An extrasolar planet, or an exoplanet, is one which orbits a star other than our Sun. These planets provide interest and opportunities for research, because under the correct conditions, such as those upon Earth, there is a possibility that life could exist and/or be discovered upon these planets. By observing exoplanets, and specifically searching various… Continue reading Some Planets Are Just So Extra… (Extrasolar, That Is)Continue reading Continue reading

Potentially Hospitable Exoplanets

One of the most exciting thoughts for many is the possibility of life on another planet. With our Solar System being explored without success, the search has spread to other systems for a hospitable exoplanet. An exoplanet, also know as an extrasolar planet, is simply a planet outside of our solar system. The goal for […]Continue reading Continue reading

Extrasolar planets

image source In the class, we learn about the astrometric technique, Doppler technique and direct imaging used to detect extrasolar planets. And in this blog, I’d like to introduce some other planet-hunting strategies that have proved to be applicable. The first method is called gravitational microlensing. A gravitational microlensing occurs only when two stars are […] Continue reading Continue reading

Rocky Planets Shouldn’t Get This Big…

Planetary formation theorists are scratching their heads at the recent discovery of the largest rocky world found to date – BD+20594b. This exoplanet is a rocky world with a diameter half that of Neptune. With a planet that size, one may think that we were talking about a gas giant, but we’re not. According to our present […] Continue reading Continue reading

The Hunt for Extrasolar Planets

The Hunt for Extrasolar Planets 2098 extrasolar planets have been discovered starting in 1988. Extrasolar planets are planets that exist on stars other than the sun. Because these are relatively small and dark object that orbit much larger bright objects so very far way they can be very difficult to find. Astronomers can discover them […] Continue reading Continue reading

New Horizon’s Approaches Pluto: So What?

NASA’s New Horizon’s spacecraft is only three months approaching Pluto, and for the first time, we have a true color picture of the Pluto/Charon dwarf planet system. As I sit here typing this, I say, “so what?” Well, it turns out that this is the first time that any spacecraft has traveled so long and […] Continue reading Continue reading

Could our Solar System have once had Super Earths?

New research appears to suggest that the early solar system might have been home to several “Super Earths,” terrestrial planets which are between 1 to 10 times the mass of Earth. One of the lingering questions about the formation of the solar system involves exactly how is it that the terrestrial planets of our solar system are so […] Continue reading Continue reading
