Water didn’t come from comets, Rosetta analysis shows

Rosetta's extremely interesting analysis raises even more questions than it answers. Image via ESA.

As you might remember, a few days ago we were telling you about the fantastic success of the Rosetta mission – a spacecraft launched by the European Space Agency which orbited a comet and sent landed a probe on it. Now, we already have the first result: Earth’s water probably didn’t come from comets. Did you ever ask yourself where…

Pulsars with black holes could hold the ‘holy grail’ of gravity

Pulsars and black holes, two of the most enigmatic celestial bodies in the Universe may actually hold the key to understanding how Einstein’s theory of relativity and gravity interact. A pulsar is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. Pulsars are from when a star that turns becomes a supernova and then collapses into a neutron star;…

Organic molecules found on comet

The Philae lander found organic molecules on the surface of a comet.

As we were telling you already in several articles, the Rosetta probe is in orbit of a comet – the 67P/Churyumov-Gerasimenko comet. But to make things even more exciting, Philae, Rosetta’s lander, also made contact with the comet; among other things, the lander found carbon molecules on the comet – the basis of life on Earth. Considering how comets are believed to…

A group from the Laboratory of Astrophysics of Bordeaux, France, and the National Centre for Scientific Research (CNRS) has made a most exciting discovery. The astronomers found that an odd binary system – a solar system comprised of two stars – actually behaves like a double star, with two disks of matter encircling the system in a beautiful dance of gas and…

Here’s something you don’t see everyday – for the first time, astronomers witnessed how a nova is formed right from the onset, capturing and detailing its expansion. The white dwarf turned nova is located some 14,800 light-years away and its study is set to reveal many things about how novas form. The star is dead, long live the nova! Stars shine…

Mind-Blowing $1.4 billion Thirty Meter Telescope begins construction in Hawaii


After years of planning and engineering schemes, the construction of the $1.4 billion telescope in Hawaii has finally begun. The unimaginatively named Thirty Meter Telescope (TMT) will provide astronomers with unparalleled power to observe the stars – it will have a resolution 10 times better than Hubble. The telescope is designed for observations from near-ultraviolet to mid-infrared (0.31 to 28 μm…

Our sun is but a tiny speck of light among billions, part of the spiral galaxy we familiarly call the Milky Way. That in itself makes us puny humans feel extremely humble, but things get really out of proportion when you zoom out. Galaxies on their own turn congregate in the hundreds or even thousands, bound together by gravity to…

ESA’s billion-star surveyor, Gaia, ready to begin its science mission

Artistic representation of the ESA.

Gaia is an unmanned space observatory of the European Space Agency (ESA) which aims to catalog approximately 1 billion astronomical objects (mostly stars), about 1% of the Milky Way population. Gaia will provide a trove of valuable and spectacular data, including a precise three-dimensional map of astronomical objects throughout the Milky Way and map their motions. We were telling you…

101 Dalmatians ?! Probe counts and maps the geysers on Enceladus


The geysers on the surface of Saturn’s moon Enceladus have been counted and mapped, strengthening theories that Enceladus is one of the best extraterrestrial places in our solar system to look for life. Earth is not the only place in our solar system which holds water. For example, Enceladus also has liquid oceans – albeit ones covered by a thick…
