Distance in exoplanets – a problem?

© Afrim Constantin –

The space telescope NASA is special because it is the first to take measurements of parallax in microlensing to accurately calculate the distance of distant planet. In this case, OGLE-2014-BLG-0124 was observed at 13,000 years light from us. Using NASA’s Spitzer Space Telescope and the Warsaw Telescope at Las Campanas Observatory in Chile (as part

The slow interaction of dark matter

© Afrim Constantin –

For the first time, the dark matter may have been observed in interaction with other dark matter in a different way by the gravitational attraction. The observation of colliding galaxies carried out with the VLT (Very Large Telescope) ESO and the Hubble Space Telescope NASA / ESA has permission to collect the first interesting clues

Exoplanet with an infernal atmosphere

© Afrim Constantin –

Data collected by HARPS spectrograph (ESO in Chile) combined with those obtained from the Hubble have allowed Swiss researchers to study in detail the violent, turbulent and very misty atmosphere of HD189733b. The winds blow at over 1000 kilometers per hour. From the beautiful blue color which is depicted would not seem, but the exoplanet

Liquid water on Mars

© Afrim Constantin –

A study conducted by researchers at the Mars Group at the University of Copenhagen shows that water can exist in liquid near the Martian surface. The discovery has been obtained thanks to the discovery of perchlorate in the soil calcium, a substance which allows keeping the water in the liquid state, in the form of

The movie of Milky Way

© Afrim Constantin –

The more accurate reconstruction of the history of star formation in galaxies similar to our offers us the best vision of what may have happened in the course of billions of years, even in the Milky Way. A kind of ‘film’ made up of many frames, about 2,000, each representing a snapshot of the state

Extragalactic neutrinos on the wings of GRBs

A model published this week in Nature Communications, from the data of IceCube, reconstructs the production process more types of astroparticle by the gamma-ray burst. It shows how the different outcomes are a result of the non-uniformity of their internal structure. Gamma-ray bursts as intergalactic highways. This analogy was chosen by Mauricio Bustamante, of Ohio

Old stars in young body

© Afrim Constantin –

An international study with several Italian researchers discovered red giant stars that are older if we look at their chemical composition, but considered young by the internal structure. Comment by Cristina Chiappini (AIP) and Josefina Montalban (INAF). Red giant stars with the chemical clock malfunctioning. And this was discovered by an international team of astrophysicists,

The seasons of the Sun

© Afrim Constantin –

Our star is subject not only to an eleven-year cyclical trend, but also a kind of seasonal variability, much shorter. This hypothesis is advanced by a team of researchers and published in the journal Nature Communications. We have learned, starting from the observation of the number of sunspots and gradually, more and more in depth
