Valles Marineris is the largest canyon on Mars, and in the solar system for that matter that we know of. It’s 4000 km long, 200km wide, 10 km deep and stunningly beautiful. Just so you can get a glimpse of how beautiful it is, ESA just recently posted a movie that focuses on an enclosed 8 km-deep […]
Physicists today and the theories they currently elaborate are seemingly entrenched in one major idea: that the Big Bang occurred once in a moment of singularity (infinitely dense Universe) and has expanded ever since. Christof Wetterich, a theoretical physicist at the University of Heidelberg in Germany, has an alternate view. He believes the Universe is not […]
Every little thing we hold for granted here on familiar ground and gravity is different in space. Take washing your hair for instance. Expedition 36 crew member Karen Nyberg recently uploaded a video on YouTube which has since gone viral which demonstrates how astronauts aboard the International Space Station wash their hair in microgravity. At first […]
NASA and a company called Aerojet Rocketdyne recently finished testing a rocket engine injector created purely through 3D printing. The future – today 3D printing is pretty much what it sounds like – it is a process of making a three-dimensional solid objects of virtually any shape from a digital model. Adopting the technique even […]
An US astronomer recently reported that he and his team have discovered a new moon orbiting the eighth and farthest planet from the sun, Neptune. Designated S/2004 N 1, this is the 14th known moon to circle the giant planet. Some of you might find it odd that we’ve yet to spot all the moons orbiting […]
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 otherwordly new video features one of the two Martian moons – Phobos, as it rises on the sky. Even though the movie only has 32 seconds, the action actually took place over the course of 27 minutes. Mars has two moons: Phobos (which is just 22 km wide on average), and Deimos, which is […]
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 […]
Pluto may not be a planet anymore, but it still has a few moons. The International Astronomical Union (IAU) is announcing that the names Kerberos and Styx have officially been recognised for the fourth and fifth moons of Pluto, which were discovered in 2011 and 2012. Both the names come from Greek mythology. Kerberos (or […]
The Fermi Space Telescope has catalogued the 514 most powerful objects in the Universe, that we know of. Astrophysicists don’t know what over 10% of them are. Why 514? The idea was to catalog the objects which emit γ-ray sources at energies above 10 GeV. What’s a GeV? It stands for Giga electronvolt, which […]
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 […]
Scientists from Department of Earth Sciences at the University of Oxford have analyzed the compositions of Martian meteorites found on Earth and data from NASA’s rovers, and they reached the conclusion that the Red Planet had an atmosphere pretty rich in oxygen 4 billion years ago. They compared Martian rocks with meteorites, and the fact […]
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 […]
A near-Earth object (NEO) is a Solar System object whose orbit brings it into proximity with Earth; now, the 10.000th near-Earth object, asteroid 2013 MZ5 was discovered, on the night of June 18, 2013, by the Pan-STARRS-1 telescope located on the summit of the Haleakala crater on Maui. Out of the 10.000 discovered NEOs, over […]
Musica Universalis or Music of the Spheres is an philosophical concept which portrays the proportions in the movement of the celestial bodies – the sun, planets, stars and so on – as a form of music. These observable patterns aren’t quite musical, since they lack harmony, but the idea itself has influenced a great of […]
More and more discoveries seem to hint at a watery past for Mars. Now, NASA research shows that hunks of frozen carbon dioxide (dry ice) may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing away as they go down. This study could explain one of the mysteries of […]
Typically on Earth, days usually have a temperature maximum somewhere after lunch, and a minimum during the night. But for Mars, things are pretty different: “We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight,” said Armin Kleinboehl of NASA’s Jet Propulsion Laboratory […]
Astronomers have discovered 26 likely black holes in the Andromea Galaxy – the biggest number of black holes ever found in a galaxy except for our own. Black holes are pretty difficult to detect, because they emit no light of their own – they are only observed by light given off by material which falls […]
An extremely rare and small galaxy has just been reported by astronomers, which by all accounts can be considered the least massive galaxy discovered thus far. The very faint galaxy, consisting of roughly 1,000 stars, supports current theories relating to the formation of the Universe. Located in the constellation Aries, the dwarf galaxy dubbed Segue 2 […]
Early galaxies were very different from those we see today – it was overgrown black holes, and not stars that lit them up, claims a new study; in it, it is suggested that these obese black holes were numerous and bright enough that we should be able to detect them now, billions of years […]
If you’re a regular follower of NASA’s updates, you may have caught glimpses of some of the X-ray photos they report showing the surface of the sun. In these photos, dark specks of various sizes can be seen, which are actually what astronomers refer to as coronal holes. They may extend from the Sun’s equator to […]
Stars have a pull on all planets, but they exhibit a special kind of attraction towards a class of planets called ‘Hot Jupiters‘. Hot Jupiters, also called roaster planets or pegadisds are a class of extrasolar planets very similar to Jupiter, but which have very high temperatures because they orbit very close to the Sun. […]
Towering thunderstorms are a bad sign, often announcing a strong tropical cyclone – and NASA’s satellites observed just that. The TRMM satellite spotted thunderstorms reaching heights of almost 9 miles high within Tropical Storm Andrea, while the Aqua satellite provided an infrared view that revealed very cold cloud top temperatures that coincided with the towering […]
As we’ve already posted today, NASA’s GRAIL mission did a great job of mapping out the gravitational features of the Moon. Just as a quick add to that, here’s two maps which I hope you’ll find interesting:
Detailed analysis and review have confirmed the scientists’ initial opinion – the pebble containing slabs Curiosity stumbled upon last year were indeed part of an ancient streambed. When the Curiosity rover landed on Mars, it was expecting to find lots of things – but finding evidence of ancient water so close to the land site […]
NASA’s GRAIL mission had been studying the Moon’s gravitational field for 9 months, with great results – they have discovered the massive regions which cause irregularities in the Moon’s gravitational field, making it uneven. Planetary gravitational fields The Earth, the Moon, and pretty much all planets have irregular gravitational field – first of all because […]
Black holes are the single most interesting and puzzling objects in our Universe – that we know of. But as if they weren’t mysterious enough, researchers have found that if you apply a quantum theory of gravity to these bizarre objects, the all-crushing singularity at their core disappears, opening a whole new Universe of possibilities […]
In a never-before seen feat, astronomers using NASA’s Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, something which can provide valuable clues to understanding these mysterious objects. Neutron stars Neutron stars are the cores of former high-mass stars, the remains of supernovae after the blow-up. As the core of the massive […]
It’s the outskirts of our solar system – spherical particles of rocks and ice, way beyond the familiar planets, and even the former planet Pluto, there lies the Oort Cloud – a spherical cloud of predominantly icy planetesimals that may lie roughly 50,000 AU from the Sun (AU = the distance from the Sun to […]
Well the title may be a little flashy, but here’s what it’s about: some highly unusual minerals have been found at the centers of impact craters on the moon. Geologists working on the case believe that they may be the shattered remains of the space rocks that made the craters, but didn’t exhume any material […]
The “Ring Nebula” is a very popular target for amateur astronomers around the world since its bright glow and highly characteristic shape make it easily identifiable, even to those who have yet to learn even the most basic tricks of the trade. This fantastic cosmic cloud tells the story of a dying star and for […]
A team of Canadian researchers has discovered a bacterium that thrives in the Arctic regions, much below freezing point, at -15 degrees C in one the coldest temperature ever reported for bacterial growth. The discovery of the bacterium Planococcus halocryophilus OR1 was made in Ellesmere Island, Canada, a part of the Canadian territory of Nunavut, […]
In April, the Russian space agency launched the Bion-M craft which carried quite a few mice, gerbils, newts, snails and some microfauna into Earth’s orbit. The experiment was designed to test how weightlesness affect them and how these organisms adapt in the process. The craft returned back to Earth on May 19th in an otherwise […]
In March, a medium sized meteorite slammed into the moon’s surface causing the greatest explosion observed thus far, ever since the moon’s surface was first monitored by NASA looking for such events eight years ago. The meteorite collided with the moon at a mind-boggling 56,000 mph (90,000 kph), creating a new crater 65 feet wide (20 […]
Buried deep at some 2.4 kilometers beneath the surface, in the vicinity of an underground mine near Ontario, Canada, scientists have stumbled across what may actually be the oldest water on Earth. Isolated for more than a billion years, the water pocket holds invaluable clues that may hint how ancient life formed, while also shinning hope that […]
Dire news came today. Astronomers, and people dreaming of life beyond our solar system alike all over the world, are morning the loss of the Kepler – the space telescope tasked with discovering exoplanets capable of supporting life. One of the telescope’s wheels failed and as such, the telescope can’t stabilize its gaze on a […]
Hubble just never ceases to surprise. The latest astronomical find discovered using the ever resourceful space telescope is a never before encountered double ring pattern known as an Einstein ring. This very rare pattern is the result of a peculiar optical alignment in which three galaxies are perfectly aligned with each other, like beads on […]
A new alien planet has been found by astronomers who have a novel planet hunting method which makes good use of Einstein’s special theory of relativity. The newly found exoplanet is slightly larger than Jupiter and is the first such planet found with this method. The planet orbits a star in the constellation Cygnus, about […]
This Thursday marks a special occasion for star gazers once with the setting of the annular eclipse, an event which Earth, the moon and the sun align such that only a ring of light around the moon will become visible. Unfortunately, only those living in the Pacific area will be able to see it in […]
Two fantastic space telescopes, Hubble and ESA’s Herschel, have teamed up to image one of the most popular astronomical sights in the sky, the “Horsehead” nebula, in infrared as well as longer wavelengths to provide unprecedented insights as to what’s going on in this stunning star hatchery. Listed in catalogues under “Barnard 33”, but better known […]
The ever resourceful Kepler mission has recently unveiled several new possible Earth-like planet candidates, two of whom are favored by scientists with the best odds yet of supporting alien life. The pair actually orbits around the same star, called Kepler 62, after NASA’s Kepler spacecraft, which is smaller and dimmer than our own star. Kepler 62 […]
Renowned physicist, famous for his study of black holes, galaxies and for authoring a popular book on the origin of the universe, “A Brief History of Time”, recently arrived at Caltech, like every year, where he held a talk in front of 1,000 people who had waited in line for 12 hours to hear him speak. […]
After much heated discussions, Hawaiian officials have granted a permit which will finally allow the highly anticipated Thirty Meter Telescope (TMT) to be built on the site of the Mauna Kea summit. Once completed it will stand as the largest optical telescope in the world, allowing astronomers to achieve things they’ve only dreamed about in the […]
New observations have tracked the “rain” of charged water particles over Saturn spewing from its rings with unprecedented detail. The findings show that the rain is dispersed across a larger surface of the planet than previously thought, which might explain some peculiar meteorologic phenomenae. The study concludes that due to erosion, Saturn’s icy rings discharge […]
Billions of dollars and decades worth of research have been invested in fusion propelling technology, so that one day we might breach current spaceflight limitations that offer little hope of straying too far from our planet. Researchers at Washington University have recently made great strides forward in this respect and have successfully tested each stage […]
Billions of years ago, Mars had a much richer atmosphere than it has today, which is rather an understatement considering how thin it is. Some scientists hypothesize that once Mars was capable of holding liquid water at its surface, with recent evidence adding weight to these claims. Recent measurements made by Curiosity‘s instruments highlight a […]
One of the most mysterious, and weirdest at the same time, phenomenae in quantum physics is quantum entanglement, in which two connected particles can share information instantly despite being separated, no matter the distance. Two particles, or so the theory holds, could be parted by light years in distance and still reflect each others’ stances instantly, […]
Astronomers using NASA’s Hubble Space Telescope have come across the farthest supernova of its type found thus far – a type Ia supernova which exploded some 10 billion years ago. The discovery isn’t just about setting milestones, however. Supernovae act as beacons that help astronomers measure the expansion of the Universe, and this latest finding will help […]
A magnetic solar ‘heartbeat’ beats deep down in the Sun’s interior, generating energy that leads to solar flares and sunspots. Solar flares and sunspots A solar flare is a large energy release in the form of a sudden brightening of the surface or the solar limb. The flare ejects clouds of electrons, ions, and atoms […]
A $1.6 billion cosmic ray experiment on the International Space Station has come across evidence of antimatter in space, a remarkable finding that was recently presented during a seminar at CERN and which might help probe the mysteries of dark matter – one of the major components that make up the Universe. The find was made using […]
