A new study has concluded that virtually all red dwarfs, the stars which make up at least three quarters out of all the stars in the Universe, have planets orbiting them. The study suggested that habitable-zone super-Earth planets (where liquid water, and therefore life as we know it can exist) orbit around at least a […]
In light of recent NASA budget cuts, a lot of politicians, citizens and, frankly mostly non-science folks, reflect that money should be funneled to other more, immediate goals: education, health, fighting unemployment etc. The rhetoric goes by the familiar terms that there isn’t any reason for man to venture outside the planet, until he at […]
A piece of rock traveling at at 61,000 km/h punched a crater 40 metres wide on the surface of the Moon, producing a flash that could be seen from Earth. I feel like Hollywood can ruin your expectations when talking about huge meteoritic impacts – we’re dealing with a meteorite here that’s way smaller than […]
I think many of us wanted, at some point in our lives, to become astronauts. Unfortunately, not so many of us actually make it – but that doesn’t mean we can’t help. With only a laptop or a tablet, YOU can help astronomers discover black holes from the comfort of your couch. An international team […]
In the past two decades alone, some 900 exoplanets – planets outside our solar system – have been identified, with some 2300 more in queue. Most of these were confirmed using the now discontinued Kepler space telescope. It’s remarkable how much scientists can find out about a distant plant, hundreds of light years away, simply […]
NASA recently announced that it will be tasking the Curiosity rover, currently exploring Mars’ surface at the Gale Crater, with a new mission that wasn’t included in the initial plan. After Curiosity provided some of the most fantastic scientific clues in recent history when it found evidence that Mars could have supported certain kind of […]
The discovery of a giant planet orbiting its star at 650 times the average Earth-Sun distance baffled researchers. So far, they haven’t been able to explain how such a strange system came to be. The international team of astronomers was led by a University of Arizona graduate student. This is the most distant planet ever […]
Using the Hubble telescope, astronomers have identified faint signals of water in the atmosphere of five exoplanets. The alien planets, however, are classed as hot-Jupiters – huge planets with a surface temperature too hot to support life. Finding water on planets light years away from Earth is definitely of great note and marks a step […]
It’s a big, bad, lava world – and according to what we know about astronomy, it simply shouldn’t exist. Kepler-78b circles its star every 8 and 1/2 hours, featuring one of the tightest known orbtits. According to currently accepted theories on planetary formation, it couldn’t have formed so close to its star, nor could it […]
Although the Kepler Space Telescope itself is defunct due to a malfunction that rendered it out of operation some months ago, the mission goes on as scientists churn through massive amounts of data gathered by Kepler, enough to keep them busy for years to come. One of the fruits of Kepler is an exoplanet called Kepler […]
An international discovered a young, exotic, rogue planet – PSO J318.5-22, is just 80 light-years away from Earth and has a mass six times that of Jupiter; it was formed apporximately 12 million years ago – which makes it a newborn in terms of planets (the Earth was formed approximately 4.5 billion years ago. “We […]
A lost moon of Neptune has not been seen since its discovery in the late 1980s – until now, that is. A new announcement from the 45th Meeting of the Division for Planetary Sciences of the American Astronomical Society revealed the rediscovery of the moon of Neptune which was only glimpsed briefly back in the […]
Astronomers have created the first cloud map of a planet outside our solar system, a sizzling, Jupiter-like world known as Kepler-7b. NASA’s Kepler and Spitzer space telescopes found patchy clouds on this hot Jupiter which was discovered in January 2010. Hot Jupiters are some of the most common planets from what we know so far; […]
NASA’s Cassini spacecraft has detected propylene, a chemical used greatly in everyday life, in things like food-storage containers, car bumpers and other consumer products, on Saturn’s Moon Titan. I really recommend watching the video below, as it explains the situation in great detail: A small amount of propylene was identified in Titan’s lower atmosphere by […]
After finding no methane in the Martian atmosphere, Curiosity has shown that the soil and dust on the surface of the Red Planet contain a few percent water, judging by weight. Yes, yes, I know, Curiosity has found signs that water flowed on Mars sometime during its past (1, 2, 3), but this time, it […]
If you were to look at them from the safety and serenity of your home, the gas giants of our solar system seem to be quite peaceful. Their surface appears smooth, unscathed by meteor impacts or other such phenomena – but this couldn’t be further from the truth, as they sometimes show us. In 2010, […]
Some 5.000 years separate us from the birth of Ancient Egypt, in 3.100 BC. Add another 5.000 years, and you still haven’t reached the date when Göbekli Tepe was built. The temple (now in southern Turkey) took shape over 11.000 years ago, around the same time Plato’s hypothetical Atlantis goes under, 5 millennia before the […]
As we know by now, most galaxies, including our own, have a supermassive black hole at their center. However, the one in our galaxy, Sagittarius A* (pronounced Sagittarius A-star) has a surprisingly small appetite, something which has puzzled astronomers for years. Sagittarius A* is 4 million times as massive as the sun, but it is […]
Launched just month, NASA’s IRIS telescope which is currently orbiting Earth has already beamed down its first images of the sun. The details are unprecedented, as scientists can now study a multitude of thin, fibril-like structures that have never been seen before, revealing enormous contrasts in density and temperature. The telescope’s main mission is that […]
The world, known as HD189733b, has a deep azure hue, probably the result of molten silicate glass rain in the atmosphere, which scatters blue light. The giant planet is one of the closest and most studied in the exoplanets recently discovered; it is a sauna, a hazy hothouse swept by blow-torch winds powered by the […]
The overwhelming part of the universe is still a mystery to astronomers – and most of what we know is a result of deduction and analysis. So it should be no big surprise that when radio waves from 11 billion light years was received, they couldn’t pinpoint its origin. Their brightness and distance suggest that […]
Although astronomers have identified less than a dozen potentially habitable planets so far, a new study suggests that our galaxy may be teeming with planets actually capable of hosting life. Based on data from NASA’s planet-hunting Kepler spacecraft, researchers had previously predicted that there should be one Earth-sized planet in the habitable zone of each red […]
The Voyager 1 has truly gone where no man has gone before – the brave shuttle is now more than 11 billion miles (18 billion kilometers) from the sun, closer and closer to becoming the first man-made object to reach interstellar space. To me, it’s just baffling that we sent something 18 billion kilometers from […]
In an unexpected discovery, astronomers have surprised a supermassive black hole that had been dormant for the past decades “waking up” and feasting upon an unsuspecting planet that had drifted too close to its event horizon. The mass of the planet hints towards a giant Jupiter or a small brown dwarf. Also, a similar event […]
To boldly go where no man has gone before: a spacecraft launched from Earth, Voyager I has pushed into the great unknown, leaving behind our solar system. For years, astronomers have been discussing about when Voyager will finally leave the solar system – and it’s actually pretty hard to draw a line and say that […]
Despite all the magnificent advancements in the field, we are still in the infancy of our research on extraterrestrial planets, so it shouldn’t really surprise anybody if a new type of planet is found. Mysterious dense bodies outside the Solar System which have puzzled astronomers for quite a while may in fact be remnants of […]
A new analysis of data from NASA’s Lunar Orbiter Laser Altimeter (LOLA) shows that molten rock created by lunar impacts has been around for much longer than previously believed. During its earliest days, the Moon was covered in an ocean of molten rock, pretty much like every planet out there. As that lunar magma ocean […]
A pair of newly discovered stars is the third-closest star system to the Sun – the closest astronomers have found a star system since 1916. The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University. Both stars in the system are brown dwarfs – not exactly stars, […]
Researchers have for the first time conducted a remote reconnaissance of a distant planetary system with a new telescope imaging system. Peeking at other planets Project 1640 is a dedicated high contrast imaging program at Palomar Observatory with the goal of obtaining images and spectra of brown dwarfs and planetary mass companions to nearby stars. […]
Researchers have, for the first time, calculated the distance to the Large Magellanic Cloud, a galaxy neighboring the Milky Way. Care to take a guess? According to these calculations, it’s just 163.000 light-years away. For measurements inside our solar system, researchers use a technique called parallax. Parallax is a displacement or difference in the apparent […]
Astronomers using ESO’s Very Large Telescope have obtained what is likely the first direct observation of a forming planet still embedded in a thick disc of gas and dust. If the finding is confirmed, it could significantly boost what we already know about forming planets. An international team led by Sascha Quanz (ETH Zurich, Switzerland) […]
A ring of radiation that scientists knew nothing about fleetingly surrounded our planet last year, before being blown away by a powerful interplanetary shock, researchers say. Astronomic intuition Usually, whenever NASA launches a spacecraft, they wait weeks or even months to finely tune all its instruments. It’s a rite of passage that all shuttles (and […]
A metal poor star located in the Milky Way galaxy, “just” 190 light years away from our Sun is 14.46+-0.80 billion years old – nearly as much as the age of the Universe! All stars follow a stellar evolutionary path; by knowing some parameters about the star (such as mass, luminosity, and surface temperature), astronomers […]
A telescope in Chile recently imaged one of the brightest spots at the core of the Milky Way, beautifully illustrating a star cluster and its neighboring dark nebula. The latter offers a stunning contrast for the billions of stars present in this patch of our galaxy. This fantastic view was made possible using the Wide Field […]
Our galaxy is teeming with billions of planets very much like our own, a new research suggests – many of them circling a star similar to our Sun. Earlier research suggested that if you want to find planets like our own, you must first find stars like our own; but a fresh analysis from the […]
It was a mystery that kept astronomers scratching their heads for years, but now, it finally seems to be cracked: particles from inside the solar system bounce off a “ribbon” of energy boundary and neutral atoms from that collision stream inward. Why and how this happens remained a mystery for quite a while. Basically, this strange […]
As our search for alien planets improves and intensifies, astronomers are starting to pay more and more attention to one crucial aspect of alien planets: whether they fit into the ‘habitable zone‘ – the so-called Goldilocks area in which a planet is not too close and not too far from its star – just perfectly […]
Close, but not too close – an asteroid like that can crash on our planet every 1200 years, but there’s no reason to worry, even though it will make a flyby on February 15, passing at a distance of only 26.780 km. For comparison, the distance to the Moon varies from around 356,400 km to […]
Astronomers are baffled by a pulsar heavier than the Sun and smaller than New York which alternatively switches on and off between radio and X-ray emissions. Small and heavy Pulsars are highly magnetized, rotating neutron stars, with a radius in the order of about 10 km, made up of neutrons. It is the result of […]
Researchers from Leicester University have shown that auroras (similar to Earth’s aurora borealis) occur on other bodies outside our solar system. Aurora borealis Aurora borealis is a natural light display occuring in high latitude areas (both north and south), caused by the collision of energetic charged particles with atoms in the high altitude atmosphere. Here’s […]
The most powerful explosion in the Universe – a gamma-ray burst– might have hit Earth during the middle ages. Luckily enough for our ancestors the event had its origin thousands of light years away and its effects went by unnoticed. Last year, scientists found unusual levels of radioactive carbon-14 in cedar trees in Japan and spikes […]
The first sample from underground Mars will come from a rockbed that showcases unexpected mineral veins of gypsum. A Martian candy store Astronomers and geologists are now in the equivalent of a Martian candy store of scientific objectives: the lowest point of Gale crater, called Yellowknife Bay is literally teeming with minerals that could only […]
In a novel and highly praised research, a team of astronomers have managed to estimate the mass of our host galaxy with unprecedented accuracy, findings suggesting it is in the order of 1,6 trillion suns. Astronomers estimate there are between 200 and 400 billion stars in the milky way. Estimating the mass of the Milky […]
The North Star (or Pole Star) has been a guiding light for generations of navigators. But a new study conducted on it claims that the distance from the star to Earth has been grossly overestimated – by 30 percent, actually. Polaris is about 323 light-years away from our solar system, an international team explained, 30 […]
Astronomers using ESO‘s Very Large Telescope (VLT) have discovered the most powerful quasar outflow discovered to date – five times more energetic than the previous record holder. Dubbed SDSS J1106+1939, the quasar outflow is at least equivalent to two million million times the power output of the Sun or 100 times higher than the total power […]
Astronomers have for the first time confirmed a bridge of hot gas with a temperature of about 80 million degrees Kelvin connecting a pair of galaxy clusters 10 million light-years apart. The discovery is of particular importance since it might help shed light on the missing baryonic matter that has been puzzling scientists for decades. The […]
Like in a scene from a Sci-fi novel, about 100 light years away, somewhere in the constellation Doradus, a planet is travelling around the galaxy by itself, without orbiting a parent star. This “rogue planet“, has a temperature of about 400C and a mass between 4 to 7 times that of Jupiter – close to […]
A startling study, which looked at data 10 times more comprehensive compared to previous similar efforts, found that half of all the stars that have ever existed were created between 9 and 11 billion years ago, with the other half created in the years since. What this means is an exponential fall in new stars being […]
Astronomers at UCLA university have made a remarkable discovery, after they’ve confirmed the presence of a star orbiting the black hole at the center of our galaxy in a mere 11-and-a-half years – that’s the shortest known orbit of any star near this black hole. The researchers involved in the paper describing the find claim that […]
Ok, it’s not actually blue, but this is what two full moons occurring in the same calendar month are commonly referred to. This month of August, the skies will be blessed with not one, but two full moons, the first on Aug. 1 and the second on Aug. 31 – don’t mean burst your bubble […]
