3 arcmin × 3 arcmin Chandra X-ray image of the pulsar vicinity in 0.5–10 keV range smoothed with a 25 pixel Gaussian kernel. The ‘+’ symbol shows the pulsar position. The ‘jet’ and ‘counter-jet’ are marked. The 30 arcsec × 30 arcsec image part, enclosed by the cyan dashed box and smoothed with a 3 pixel Gaussian kernel, is enlarged in the inset. The possible PWN torus and the base part of the ‘jet’ are marked.

X-ray study sheds more light into the nature of a gamma-ray pulsar

Using archival data from ESA's XMM-Newton spacecraft and NASA's Chandra X-ray observatory, astronomers have investigated one of gamma-ray radio-quiet pulsars known as PSR J1826−1256. The study, based on X-ray observations, ...

New algorithm digs up 18 Earth-like exoplanets from old Kepler data

So far almost 4,000 planets have been discovered orbiting stars other than the Sun, and that tally is constantly growing. Now another 18 exoplanets have been added to the haul, ...

Advanced civilizations could be communicating with neutrino beams

In 1960, famed theoretical physicist Freeman Dyson made a radical proposal. In a paper titled "Search for Artificial Stellar Sources of Infrared Radiation," he suggested that advanced extra-terrestrial intelligences (ETIs) ...

Gaia's all-sky-view, showing the clear center of the Milky Way and the galactic disc

“Stellar baby boom” may have given birth to half the Milky Way’s stars

About a year ago, the European Space Agency (ESA) released the Gaia galactic census that detailed the position, distance and motion data of almost 1.7 billion stars in the Milky ...

Computer simulation of the formation of a proto-cluster of galaxies. Supermassive black holes may have had an important role in the formation of these structures in the early Universe.

Forecasting the hunt for the first supermassive black holes

It is believed that the formation and growth of most galaxies across the history of the universe has been fueled by supermassive black holes growing together with their host galaxy ...

An artist's concept of super-Earth planet 55 Cancri e, which races around its host star once every 18 hours. New research led by Penn State astronomers improves our understanding of how large super-Earth planets with small, quick orbits form.

Gravitational forces in protoplanetary disks may push super-Earths close to their stars

The galaxy is littered with planetary systems vastly different from ours. In the solar system, the planet closest to the Sun—Mercury, with an orbit of 88 days—is also the smallest ...

Artist's impression shows a view of the surface of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System.

What makes a planet habitable

Which of Earth's features were essential for the origin and sustenance of life? And how do scientists identify those features on other worlds? A team of investigators with array of ...
