First discovered in 1997 and described as a new species two years later, the Indonesian coelacanth (Latimeria Menadoensis) is one of two living species of coelacanth, a deep-sea fish that closely resembles its ancestors from the Cretaceous period.Deep diver about a meter behind the Indonesian coelacanth (Latimeria Menadoensis) discovered at a depth of 144 m in North Maluku, Indonesia. Image credit: Alexis Chappuis.Coelacanths are a group of large, sea-cave dwelling lobe-finned fish (sarcopterygians). They were thought to be extinct for 65 million years, until a first living specimen was discovered fortuitously in South Africa in 1938 by a South African museum curator on a local fishing trawler. Coelacanths present several unique and intriguing features such as unpaired lobbed-fins looking much like paired fins and highly modified lungs/swim bladder. Together with lungfish, they are the closest relatives to tetrapods...

NASA Space Technology NASA has released a beautiful composite image taken by the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope of a pair of two overlapping spiral galaxies: IC 2163 and NGC 2207.This composite image shows IC 2163 (left) and NGC 2207 (right) galaxies. Image credit: NASA / ESA / CSA / STScI.The IC 2163-NGC 2207 pair is located around 114 million light-years from us in the direction of the constellation of Canis Major.The larger and more massive galaxy is cataloged as NGC 2207, and the smaller one is IC 2163.Strong tidal forces from the former have distorted the shape of the latter, flinging out stars and gas into long streamers stretching out a hundred thousand light-years.IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest...

Top Stories Tamfitronics Two-dimensional (2D) aurora images with full spectrum have been captured by scientists in Japan using the newly-developed hyperspectral camera for auroral imaging (HySCAI).Keogram of (a) all-sky camera and (b) HySCAI, and (c) time evolution of space-averaged spectrum of aurora emission measured by HySCAI on October 20-21, 2023. Image credit: Yoshinuma et al., doi: 10.1186/s40623-024-02039-y.The aurora is a natural luminous phenomenon caused by interactions between precipitating particles and the constituents of the upper atmosphere.Most of the observed spectrum consists of lines or bands of neutral or ionized nitrogen and oxygen atoms.There is a variety of characteristic colors of aurorae, such as green and red, but there are multiple theories about the emission process by which they appear in different types of aurorae, and to understand the colors of aurorae, the light must be...

NASA Space Technology A satellite checklist shows smoke from Mexico's fires defending roughly two-thirds of the Gulf of Mexico. A cloud bank is considered in direction of the tip correct.(Image credit: MODIS Land Mercurial Response Team, NASA GSFC)A total bunch of wildfires were blazing across Canada and Mexico since closing week, and new satellite pictures released by NASA articulate their private praises the smoke pouring out of some.Firefighters were scuffling with this military of wildfires, which may per chance well per chance very properly be scattered  across various Canadian provinces, in conjunction with over 30 blazes in Alberta and British Columbia and 10 in Ontario, per the Canadian Interagency Forest Fire Centre. Smoke from multiple fires flowed into the United States and blanketed Wisconsin closing Sunday (Might per chance per chance merely 12), prompting the...
