Dinosaurs Likely Cooed Instead of Roared

When we think of dinosaurs, the first thing that comes to the mind is a fearsome predator with sharp teeth and thick, heavy necks capable of producing loud, ear-shattering sound. But new research suggests that this ‘Jurassic Park’ image of dinosaurs may not be entirely true. Researchers believe there were species of dinosaurs that more likely cooed or mumbled rather than roared.

Researchers have examined hundreds of species of birds and found many of them produce sound through the skin while the beaks are kept closed. Since modern-day birds descended from dinosaurs, the findings have implications for understanding dinosaur’s vocalization. Based on these results, researchers suggest that many dinosaurs might also vocalize with a closed-mouth and perhaps produced low-pitched sounds instead of full throated roar.

New Dwarf Planet Discovered Beyond Neptune

A new tiny planet just joins the ranks of our solar system’s dwarf planet. The newly-discovered dwarf planet, named RR245, is located beyond Neptune and is roughly 700 kilometers in diameter. The planet is so distant that it takes 700 years to travel around Sun which is one of the largest orbits for a dwarf planet. Just for comparison’s sake, its orbit takes it more than 120 times further from the Sun than Earth.

The planet was spotted using Canada-France-Hawaii Telescope on Maunakea, Hawaii, as a part of the ongoing Outer solar system Origins Survey (OSSOS).

The vast majority of dwarf planet are either destroyed or thrown away from our solar system due to the chaos created by the movements of giant planets. RR245 is one of the few dwarf planets that has survived the situation along with Pluto and Eris, the largest known dwarf planets.

NASA’s Juno Spacecraft Sends First Image of Jupiter

NASA’s Juno spacecraft has sent back its first photo of Jupiter since entering the orbit of the planet couple of weeks ago. The image was taken from the spacecraft’s JunoCam camera at a distance of 2.7 million miles away from Jupiter and shows half of the planet with its famous Great Red Spot as well as three of its four moons - Io, Europa and Ganymede. Jupiter’s second largest moon Callisto is not featuring in the image.

The image was taken on June, 10, just six days after the spacecraft arrived the planet’s orbit.

A New Dinosaur Speices has been Discovered in Argentina and It has Tiny Arms Like T. Rex

Researchers long believed that Tyrannosaurus rex were the only dinosaurs with the pair of pitifully tiny arms. But now, a new dinosaur species has been discovered in Argentina and it also has small as well as two-fingered claw like T. rex.

Despite having similar features, both dinosaur species are not closely linked to each other. Researchers believe their arms have evolved independently and have not come from a single source of origin.

Astronomers Create Largest Ever 3D Map of the Universe

Astronomers have created the largest ever three-dimensional map of universe and it charts out a whopping 1.2 million galaxies. The new 3D map will allow researchers to understand the dark energy – one of the most mysterious forces in the universe and the part it plays in the expansion of the universe.

It has been believed that dark energy is causing to expand universe at an accelerating rate. Using this map, researchers can make the most accurate measurements of dark energy and find out whether it is actually expanding universe and at which rate.
