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...
