Carnival of Space 273

Lots of varied articles this week including black holes, nuclear rockets, beam propulsion and quasars. One of the lowest mass black holes ever observed in the middle of a galaxy has been identified. By the Chandra Blog. Who would sign up for a 40-year journey, especially if it turned out to be a one-way trip? Thoughts [...]

New Rocky Type Planet Found by Kepler

The Kepler telescope, which has been looking for planets outside our solar system, has found a new rocky planet a bit like a scorched molten Earth. It orbits around a sun like star called Kepler-10 in only 45 days. It is so close to its parent star it is not expected to have any liquid [...]

Science Fiction Becomes Fact As 10 New Jupiter Sized Planets Found in Deep Space

10 new Jupiter sized planets have been found floating alone in space, and I mean alone, well away from any star. They are sometimes called orphan planets and have been the subject of science fiction and science theory for a long time but now there is evidence that they exist. The survey shows that for [...]

Jupiter Like Planet Lurking Just Outside our Solar System is Extremely Unlikely

To say that the whole astronomic community was set on fire by the claim that a Jupiter-like planet might be lurking just outside our solar system would be a bit of a stretch, but spirits were indeed high, after this claim was made by John Matese and Daniel Whitmire of the University of Lousiana-Lafayette. Tyche, [...]

Kepler Finds a Multitude of Planets of All Shapes and Structures

Some great news from the planet front has just arrived. As was expected Kepler has found lots of new planets. These planets are really planetary candidates and have to be positively confirmed but a high percentage definitely will be planets. The recent findings increase the number of planets found by Kepler to 1235. 68 of [...]

An Earthlike Planet Is Coming Soon …

One day in the future perhaps not 10 years from now we will be able to look up into the night sky at particular stars and know that they have Earth like planets orbiting them. SETI is going to scan the stars with exoplanets for intelligent life in 2011 and you never know do you? [...]

Detecting Volcanoes on Exoplanets

Volcanoes can be an indication of a planet that can support life. There are studies that show that lightning together with the chemicals volcanoes produce may have provided the spark that produced life on early Earth. This experiment called the Miller-Urey experiment has been shown to students for years from 1953 to mimic the chemical [...]

Identifying Exoplanets by Their Dust Tails

Are we losing the Sahara to space? No, is the simple answer to that. The Earth has a trail of dust behind it but the dust is interstellar dust which is already present in the solar system. This interplanetary dust comes from the fragments of comets and asteroids that have collided. As the Earth travels [...]

Would Finding an Alien Civilisation Prove or Deny the Existence of God?

Does God exist? That is a question that has been pondered over for 1000s of years since humanity could first think about his existence. Religions claim to know the answer and scientists take an objective view that is always changing as evidence appears. Most religions have to look at their beliefs differently or disregard science [...]

Actual and Artist Images of Exoplanets

Extrasolar planets or for short exoplanets have been found in orbit around many different star systems other than ours. Exoplanets are being found all the time but take a look at this database of exoplanets for an idea on their characteristics. An actual image has been shot sometime back of an exoplanet but as you [...]

How to Talk to Aliens

Lots of signals have gone into space such as TV, radar and radio. The signals have been betraying our presence for 60 years and have passed over about 6000 star systems and are reaching new systems every day. This would seem to be enough, even though we haven’t received anything back yet, but what if [...]

Kepler Mission Releases New Planets the Size of Earth and Above

Kepler is a mission to study 156,000 stars using the Kepler telescope up there in space. 706 target data has been released in a report but 400 have not. The exoplanets found have sizes from as small as Earth to as large as Jupiter. They have also found five multi planet systems which sound quite [...]

Habitable or Goldilocks zone

We live on an Earth that from day to day seems permanent and stable. We go to work, school and perhaps the pub every day and it seems like things will never change dramatically. Unfortunately as we are all beginning to realise things in the universe are forever changing which when looked at from the [...]

Closer Views on a Growing Solar System

I wrote an article on the formation of the solar system and other planetary systems throughout the galaxy a few weeks ago. New information is coming to light all the time and this is a field that has a lot of discoveries left to find. The new discoveries were published in the astrophysical Journal. Astronomers [...]

Ceres, Dwarf Planet or Asteroid?

In the previous post I made a mistake about Ceres and its classification as an asteroid or dwarf planet. It’s been a topic of debate for some time, the debate originating with Pluto and its classification from planet to perhaps an asteroid and back to dwarf planet. Everybody was once sitting pretty thinking that Pluto [...]

How to Measure the Atmosphere of Another Planet

So how do scientists find out what is in an atmosphere? Yes, this can be really interesting because when an extrasolar planet that is earth like is found in would be nice to find out if it could support life by looking at its atmosphere and the way it is made up. Obviously a nice [...]

Atmospheres of the Earth and terrestrial planets.

If you don’t know what an atmosphere is then I suggest you find a blog on fashion or similar. Perhaps, though, we think we know what an atmosphere is but do we really? Well, just in case it’s that thin blue line that we see around the Earth when looking at pictures that the International [...]

Best of the Week Podcast- A Man, A Planet and Loads of Controversy

ENCORE While the Kepler spacecraft hunts for habitable planets beyond the solar system, we’ve let one of our own planets slip away! Find out why Pluto’s demotion to dwarf status created a public uproar as astrophysicist Neil deGrasse Tyson reads us his hate mail. From third-graders! Also, how we might find Earth-like planets… the possibility [...]

Best of the Week Podcast-Hubble’s First Images of an Extrasolar Planet.

Paul Kalas was the leader of the team who managed the long-sought feat of actually taking a photograph of a planet orbiting another star. Before this, all the planets outside our solar system were found by indirect means. He describes how they achieved the breakthrough, using the Hubble Space Telescope, and discusses the wide range [...]
