Nasa has released the most colourful picture of the universe ever made. The space agency created the image by combining data from the James Webb and Hubble space telescopes to capture light that has never been seen before in one image. The picture shows the galaxy cluster known as MACS0416, which is about 4.3 billion light years from Earth. The reds, blues and bright yellows of the picture represent one of the most comprehensive views of the universe ever taken, Nasa said. The colours represent the wavelengths of light captured, going from the shortest in blue to the longest in red. Those colours also help show the distances of those galaxies. Those galaxies that are closer and more active tend to be blue, while the red ones are further away – though some are also red because the vast amount of cosmic dust in the galaxy absorbs the blue of the light from stars. It was created by gathering both visible and infrared light captured by both telescopes. The original imagery was taken by Hubble in 2014, which captured some of the faintest and youngest galaxies ever detected, and it was then combined with Webb’s infrared data to look even further into the early universe. As well as making for a stunning image, researchers are already studying the data used to create it to examine the galaxy cluster and what it might mean for the universe as a whole. The Webb observations can be used to find “transients”, which are objects that change brightness over time. In the image there are some 14 transients – most of which are likely to be individual stars that are becoming brighter, with a minority that are thought to be supernovae. “We’re calling MACS0416 the Christmas Tree Galaxy Cluster, both because it’s so colorful and because of these flickering lights we find within it. We can see transients everywhere,” said Haojing Yan of the University of Missouri in Columbia, lead author of one paper describing the scientific results. One of them in particular is notable, and has been named Mothra. The object is being magnified by up to 4,000 by a process called gravitational lensing – and is notable because it was in both the new Webb images and the original Hubble ones. Scientists still don’t know how that could happen, since the alignment of galaxy clusters and stars needed to magnify something that much is delicate and would be expected to change. Scientists believe that the likely explanation is another unseen object that could be up to a million times bigger than our Sun and is unidentified. “The most likely explanation is a globular star cluster that’s too faint for Webb to see directly,” stated Jose Diego of the Instituto de Física de Cantabria in Spain, lead author of the paper detailing the finding. “But we don’t know the true nature of this additional lens yet.” The findings are detailed in two new papers, one to be published in The Astrophysical Journal and another that already appears in Astronomy & Astrophysics.

Divers in Mexico have discovered Megalodon teeth in a flooded inland cave and the findings have confirmed scientific beliefs. Megalodons were absolutely gigantic prehistoric sharks that reached sizes of up to 50 feet long. They dominated the oceans before going extinct around 3.6 million years ago. Scientists are interested in studying fossils of the huge sea creature, with the animal's teeth proving the most abundant type of fossil to be found today. Teeth fossils were found in Mexico by speleologist (cave specialist) and photographer Kay Nicte Vilchis Zapata and fellow speleologist Erick Sosa Rodriguez while diving in a newly discovered sinkhole in Cholul in 2019. The cenote is 400 meters long and 28 meters deep and located inside were fifteen teeth fossils from various shark species. They also discovered human remains and a vertebrae fossil that potentially belongs to an ancient species. A total of 13 of the 15 teeth fossils belonged to three different species of shark – one being the megalodon (Carcharocles megalodon), while the other two species were the mackerel shark (Isurus oxyrinchus) and the sawshark (Pristiophoridae). Zapata told local media at the time: “We were looking at the wall and suddenly I saw a little something, I went closer and I saw that it was a tooth, that was the first and apparently it belonged to a sawshark.” Experts believe the geological timescale of the megalodon teeth lies anywhere between 2.5 million to 5 million years old. Speleologist Sosa Rodriguez said: “It is just proof of what scientists have already studied and written about; what kind of wildlife lived here millions of years ago when this was part of the sea.” Scientists have suggested that the megalodon’s warm body temperature may have been the reason for its extinction. There is some thought that the megalodon was able to maintain a body temperature around 7 degrees centigrade warmer than the water around it, but ultimately this may have been its downfall. Randy Flores, a UCLA doctoral student and fellow of the Centre for Diverse Leadership in Science, explained: “Maintaining an energy level that would allow for megalodon’s elevated body temperature would require a voracious appetite that may not have been sustainable in a time of changing marine ecosystem balances when it may have even had to compete against newcomers such as the great white shark.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
