The astronomers will now study more of these objects to see if galaxies are responsible for making all blobs glow. Library Glow-Worms Oxford Reading Tree: Stages 1-2: Glow-Worms: Teaching Notes Oxford Bookworms. By carefully studying the properties of the light given off by the blob shown in this photo, astronomers know that this one glows because it contains bright galaxies. research of earthworm bioluminescence occurred in the 1960s with the studies of the North American Diplocardia longa. Cat Last Chance - With Audio Starter Level Oxford Bookworms. (The tree above is more comprehensive.) If an organism is listed here it means that at least one species in that group is luminescent, not that all such creatures make light. Now, using a powerful telescope called the Very Large Telescope, which is based in a country in South America called Chile, astronomers are a step closer to solving the mystery. We had driven more than 200 miles that day, full of excitement to see a bioluminescent maggot. (2.2 MB file.) Below is a partial text list of bioluminescent organisms. The light production by these worms was at different times reported in Europe, USA, Australia, New Zealand, India, Japan, South Africa and Russia (1). Another idea is that they are glowing because there are bright galaxies inside the blobs. THE EARLIEST OBSERVATIONS OF BIOLUMINESCENT WORMS The luminescence phenomenon is not uncommon among Oligo- chaeta. One idea is that they glow when gas heats up as it is pulled in by a blob’s powerful gravity. But what is causing the blobs to glow is a mystery to astronomers. They are also some of the biggest objects in the Universe – these gigantic clouds of gas can be up to a few times bigger than the size of our galaxy, the Milky Way! Like a swarm of glow-worm insects, these blobs shine brightly. The creature lives most of its life in mucus tubes in the seabeds, but when it comes time to mate, the fireworm puts on the fireworks. These blobs are incredibly rare and very far away in the Universe. Around 2-5 days after the full moon, and around 55 minutes after sunset, the Bermuda fireworm swims to the ocean surface and flares into brilliance, lighting up with an incredible bioluminescent glow.
