This artist's illustration shows an alien world that is losing magnesium and iron gas from its atmosphere. The observations represent the first time that so-called "heavy metals"—elements more massive than hydrogen and helium—have been detected escaping from a hot Jupiter, a large gaseous exoplanet orbiting very close to its star.The planet, known as WASP-121b, orbits a star brighter and hotter than the Sun. The planet is so dangerously close to its star that its upper atmosphere reaches a blazing 4,600 degrees Fahrenheit, about 10 times greater than any known planetary atmosphere. A torrent of ultraviolet light from the host star is heating the planet's upper atmosphere, which is causing the magnesium and iron gas to escape into space. Observations by Hubble's Space Telescope Imaging Spectrograph have detected the spectral signatures of magnesium and iron far away from the planet.The planet's "hugging" distance from the star means that it is on the verge of being ripped apart by the star's gravitational tidal forces. The powerful gravitational forces have altered the planet's shape so that it appears more football shaped.The WASP-121 system is about 900 light-years from Earth. Credits: NASA, ESA, and J.

Hubble uncovers a heavy metal exoplanet shaped like a football

Space
Observations by NASA's Hubble Space Telescope reveal magnesium and iron gas streaming from the heavy metal exoplanet known as WASP-121b.
This image shows an irregular galaxy named IC 10, a member of the Local Group — a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way.

Hubble captures elusive, irregular galaxy

Cold quasars could rewrite our understanding of a galaxy’s lifecycle

Space
A Cold quasar is a galaxy with a quasar at the center and abundant cold gas that can still produce new stars. Gas falling...
This Hubble image shows the barred spiral galaxy NGC 7773. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

The striking image you can see above was taken by the ESA (European Space Agency) that features a barrel spiral galaxy known as NGC...
This image shows how the inner region of the accretion disk (red) aligns with the equatorial plane of the black hole. The outer disk is tilted away. The inner disk (where the black curve dips) is horizontal, signaling the long-sought Bardeen-Petterson alignment.

40 year black hole mystery solved with most detailed simulation ever

Space
Using a custom built code and a supercomputer, an international team of scientists has created the most detailed, highest resolution simulation of a black...
This artist's illustration shows what one of the very first galaxies in the Universe might have looked like. High levels of violent star formation and star death would have illuminated the gas filling the space between stars, making the galaxy largely opaque and without a clear structure.

Jets and winds from galaxy cores appear to share a common cause

Space
Fundamental considerations of the energy supply in large-scale extragalactic radio sources("radio galaxies") led astronomers to predict that these sources should contain jets or beams...
Astronomers developed a mosaic of the distant Universe, called the Hubble Legacy Field, that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains 200,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. The image comprises the collective work of 31 Hubble programs by different teams of astronomers. Hubble has spent more time on this small area than on any other region of the sky, totaling more than 250 days, representing nearly three-quarters of a year. The team is working on a second set of images, totaling more than 5,200 Hubble exposures, in another area of the sky.
