It’s true, Mars just had what we call a Meteor Storm. This is an event that, on Earth, only happens once every few hundred years, and the one that Mars just had was more intense than anything Earth has experienced in recorded history. This event happened because of a close Martian fly-by of comet C/2013 A1 Sliding Spring. On October 19th around 2:30pm EDT the comet came within 140,000 Km of Mars. This is incredibly close in Astronomical terms, being less than half the distance to the Moon and comparable to the total distance I’ve driven my car in the...
NASA had announced a press conference for yesterday afternoon to reveal amazing findings that would ‘change how we look at galaxies.’ And they did just that, sort of. Findings from the Cosmic Infrared Background Experiment (CIBER) reveal that there is a huge surplus of Infrared light present in the vast darkness that exists between Galaxies. Infrared light is invisible to the human eye, but is emitted by most room temperature objects. It fills the EM spectrum at wavelengths longer than visible light (See yesterday’s post for the EM spectrum). This surplus of light is greater than what we would expect from galaxies...
The Hubble Space telescope produced the finest Astronomical images in a generation, but Hubble’s time in the limelight has ended, and now it’s time for a new generation of both space- and ground-based telescopes to take over with their own jaw-dropping images and revolutionary science. Recently the Atacama Large Millimeter Array (ALMA) has taken the leap and used its full power to take an astonishing image of the protoplanetary disk of the young star HL Tau. This image is of a very young star, only about a million years old (Which is really young compared to the 4.5 billions year old...
Dark Matter; Dark Energy; We basically use the term ‘dark’ as a cool sounding version of ‘We have no clue what this is.’ But Dark Matter is a better name than ‘We haven’t a clue’ Matter. Over the years, Astronomers have been trying to pinpoint what the stuff actually is that seems to permeate the universe and makes up 26.8% of the entire total energy-mass (Compare this to a paltry 4.9% of ordinary matter, ie the stuff we can see). But now, as per usual, theorists have come up with another possibility for the source of dark matter: moderately sized,...
If you’re in Astronomy circles you may have heard about a big cloud of Hydrogen heading toward the supermassive black hole in the centre of our galaxy, Sagittarius A*. The lead up to the cloud approaching the black hole had astronomers buzzing this year, as it would be a direct opportunity for us to see the black hole ‘devour’ the cloud. The black hole would show us some celestial fireworks and give us a huge opportunity to study their behaviour. Astronomers watched closely, and then the cloud passed right by…. We should have seen the cloud torn apart as matter spiralled...
It’s been a rough week in the space flight industry. On Friday afternoon, a test flight of Virgin Galactic’s SpaceShipTwo class VSS Enterprise resulted in a catastrophe, crashing down in the Mojave desert, killing one pilot, with the other ejecting and now being treated in hospital. During the test flight, launched by Virgin Galactic’s partner corporation Scaled Composites from the Mojave Spaceport, WhiteKnightTwo, an aircraft designed to bring SpaceShipTwo to launch altitude, successfully released the spacecraft. After two minutes, something went wrong, resulting in the eventual crash of the craft. Virgin Galactic released a statement shortly after the accident, saying the National...
If you weren’t aware, new countries have entered the next space race. India’s Mars Orbiter Mission (MOM) named ‘Mangalyaan’ was successfully launched on November 1st, 2013, and has been orbiting Mars since its arrival on September 21st of this year. China has been in the mix since 2007, and have been working to gradually increase their capabilities. Their latest mission, called ‘Chang’e 5-T1,’ was launched on October 23rd, and spent 8 days travelling to the Moon, performing a flyby, and returning safely. This is the test mission before they send Chang’e 5 in 2017, a mission that will land on the...
I did a short presentation last night for a group of families at a Halloween event. My job was to talk space but make it as spooky as possible and use some Halloween themes for the kids. There really is a fine line between teaching Science and being entertaining, but here’s some of the things I did. Lets start with the following image….What does this look like to you? Did you say the head of a witch? Then yes you are right! This is known as the Witch Head Nebula. A nebula is a place where gas and dust in...
I’ve seen a lot of lovely images from the Spitzer Space Telescope. It takes infrared images and can see the fine structure of galaxies, where stars are forming and where they are not forming. The photos paint a picture of the history and evolution of a galaxy. The latest image released last week shows some amazing features. The Cyan light in the image is a combination of blue and green coloured light representing infrared wavelengths of light at 3.4 and 4.5 microns. This wavelength shows the stellar population in the galaxy. The red light is representing dust features that glow...
I was blown away to hear this news just a few hours after the launch. The Antares rocket exploded on the launchpad just six seconds after launch. Yesterday’s post discussed how the Antares-Cygnus resupply launch was delayed by a lone man in a boat who had no clue he was in the blast zone. First of all, it’s important to note that no one was hurt, including all personnel on site and in the control room. This was an unmanned rocket, so the major loss was the resupply capsule and its cargo, not to mention the loss of the $250...
