Desireé Cotto-Figueroa, an Associate Professor from the University of Puerto Rico at Humacao (UPRH) Department of Physics and Electronics has just tweeted amazing footage of a meteor over Puerto Rico, saying “Meteor just observed in #PuertoRico. Everyone who saw it please report it here.”Continue reading “A meteor has just been observed in Puerto Rico – Amazing footage”
Most exoplanets, bodies orbiting stars other than the sun, are too far away for us to be able to send probes to. So it’s no wonder that the discovery of a possible habitable planet around the sun’s nearest neighbour star, Proxima Centauri, a few years ago generated a lot of excitement. Now we have spotted what we think is a second planet around this star.Continue reading “Proxima Centauri c: how we spotted a potential new planet around the Sun’s neighbouring star”
Every season has its characteristic star constellations in the night sky. Orion – one of the most recognisable – is distinctly visible on crisp, clear winter nights in the northern hemisphere. The constellation is easy to spot even in light-polluted cities, with its bright stars representing the shape of a person.
Betelgeuse, marking Orion’s top left shoulder, is often its brightest star. Red in colour, this star is usually the 12th brightest in the entire sky. But it has recently dimmed dramatically to an all-time low of 21st brightest star in the sky. As a result, many have started speculating about whether it could be about to explode. But could it? And what would that look like?Continue reading “Betelgeuse: star’s weird dimming sparks rumours that its death is imminent”
Scientists have found the oldest material on Earth in a 7 billion-year-old meteorite – a space rock that is way older than the Earth and even older than our solar system! For comparison, the age of Earth is approximately 4.54 billion years, with an error range of about 50 million years. The Sun is about 4.6 billion years old.Continue reading “The oldest material on Earth has been found in a meteorite and it is way older than the Solar System!”
NASA and CSA (Canadian Space Agency) chose 13 new astronauts, and the good news is, almost half of them are women. Nicknamed “turtles”, six women and seven were selected men from record-breaking 18,000 applicants representing a wide variety of backgrounds and specialties.Continue reading “NASA and CSA welcomes 13 new astronauts and almost half of them are women”
A full 20 years into the 21st century, the threat of overpopulation continues to make headlines across the globe. A recent United Nations study determined that the global population, currently sitting at 7.7 billion, will increase to about 9.7 billion by 2050. That equals a 28% population increase, or approximately 82 million additional people every year. Those swelling numbers are predicted to further deplete natural resources and have detrimental effects on our already fragile natural environment.Continue reading “Investigating Overpopulation: The Causes and Effects”
Exciting news! NASA’s planet-hunter TESS Space Telescope (Transiting Exoplanet Survey Satellite) has discovered its first Earth-sized exoplanet in its star’s habitable zone. The discovery was announced by NASA on January 7, 2020. The planet is named “TOI 700 d”.
Using NASA’s Spitzer Space Telescope, astronomers confirmed the discovery and have modeled the planet’s potential environments to help inform future observations.Continue reading “NASA’s TESS Space Telescope discovers its first Earth-sized exoplanet in the habitable zone”
Leopard (scientific name: Panthera pardus) is one of the five big cat species in the genus Panthera, a member of the Felidae. The other members of the Panthera genus are Lion (Panthera leo), tiger (Panthera tigris), jaguar (Panthera onca), and snow leopard. Leopard is the fourth biggest cat in the world, after tiger, lion, and jaguar. Here are 20 amazing leopard facts.Continue reading “20 Amazing Leopard Facts”
