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 [...]


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 [...]


Latest Update on Exoplanets Lecture (July 2010)

The latest on the search for planets in other planetary systems. .


A Good Chance of Life on Mars

This is a good lecture on why there’s a 1 in 4 chance of life (in Penelope’ Bostons opinion anyway) under the surface on Mars.


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 [...]


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 [...]


The New Horizons Spacecraft Halfway to Pluto

The new Horizons spacecraft was launched in 2006 for a trip to Pluto and beyond. Unfortunately for this mission there is a little controversy about Pluto as you probably know. Pluto, to put a long story short, has been deemed a dwarf planet by the IAU and this doesn’t really suit the image that NASA [...]


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 [...]


The Different Types of Impact Craters and How to Spot Them.

A crater is simple, right? Well, not really, they are not just holes in the ground (well they are really but they do differ depending on the size of the crater). Once we have become experts on the different types of craters and why they are classified differently then I’ll go through the different ways [...]


Volcanoes on Earth and Beyond

Volcanoes are one of those great forces of nature that we take almost for granted on Earth. I am not sure that I would take it for granted if I lived right next to a volcano but on the overall scheme of things they are part of the Earth’s make up and mold the Earth [...]


Solar System Creation In a 10 Minute Read.

Wouldn’t it be good to know how you got here? Well unfortunately the answer to that is unknown. It has been thought about for a long, long time and one day we will probably know the answer. What we do have good idea about though is how the solar system formed. Throughout the galaxy gigantic [...]


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 [...]

The search for astro-engineering by SETI and others. Will these massive engineering projects seen in modern Si-Fi one day become a reality? [podcast] engineering.mp3[/podcast] Join the forum discussion on this post – (1) Posts


Kepler, Finding New Planets & Adopting A Star.

On my voyage across the Internet I bumped into something that I had been thinking about for a long time. Name a star was high up on my list of things that I must do but never got round to because I just really didn’t want to get conned. Well, I took the leap and [...]


Square Planets

Looking at the universe I have always thought it odd that planets were round and not some other shape. To make a sphere on earth isn’t really that easy.  I can’t say that I have tried it  But just trying to get a lump of plasticine into a sphere with your hands is almost impossible. On [...]
