To Pluto and beyond

© Afrim Constantin –

We have the images of the close encounter with Pluto arriving exactly half a century after the first pictures from Mars, taken by Mariner 4. Half a century to pass close to (or touch) all the planets, plus an assortment of minor bodies: satellites, asteroids and comets. Homo sapiens Planetarius completed exploration “in situ” of

Cosmic giants against dwarf galaxies

© Afrim Constantin –

A recent study reports the results of an observational campaign conducted on over 20,000 galaxies and shows that the rate of star formation as a result of a collision depends on the size of the galaxy compared to that with which it is colliding. The article can be found in the Monthly Notices of the

A premature black hole

© Afrim Constantin –

A supermassive black hole, called CID-947, has grown much earlier than expected while its galaxy continued to generate stars. And what emerges from a study published in Science led by researchers at ETH Zurich is that black holes and their host galaxies do not always evolve together, a fact that calls into question the current

Is anyone out there? HDST could tell us

A futuristic project for the heir to Hubble and the James Webb: a super-telescope with a mirror 12 meters in diameter to be placed in orbit in the thirties. For now little more than a dream, however, described in detail in a report just published by a group of USA astronomers. Take a group of

Hubble locates a ghost galaxy

The Hubble Space Telescope was designed to free the astronomers had a limitation that affected them since the days of Galileo: the atmosphere of the Earth. Airbags changing the atmosphere block and distort light, limiting the view of even the most powerful tools for use on Earth. The orbital telescopes function as eyes in the

Five monsters buried in the dust

© Afrim Constantin –

The space telescope NuStar identified a population of supermassive black holes invisible until now because of the cloud of gas and dust that surrounds them. Already it suspected the existence, but the data say they are much more bright and active than expected. This time it was not luck. They knew where to look, the

Few days ‘till the meeting

© Afrim Constantin –

There are now only about ten days meeting between the New Horizons probe and the Pluto system. No new moon discovery, but in the last images of the dwarf planet they arouse curiosity of the big dark and very regular spots. The presence of methane ice was confirmed. ‘All clear’, all alone on the route

The new maps of dark matter

© Afrim Constantin –

A preliminary survey of the sky, made a new room off the field installed at the Japanese Subaru Telescope, allowed astronomers to reveal well-9 concentrations of dark matter. The findings, published in the Astrophysical Journal, are comforting to understand the role of dark energy in connection with the expansion of the Universe. The next step
