Astronomers have found another strange exoplanet in a distant solar system. This one’s an oddball because its size is intermediate between Earth and Neptune, yet it’s 50% more massive than Neptune. Astronomers have found what they call “puff planets” in other Solar Systems. Those are planets that are a few […]

Taking advantage of a total lunar eclipse in January 2019, astronomers using NASA’s Hubble Space Telescope have detected ozone in Earth’s atmosphere. This method serves as a proxy for how they will observe Earth-like planets transiting in front of other stars in search of life. Our planet’s perfect alignment with […]

Illustration shows how the star’s motion around the center of mass between it and the planet causes a “wobble” in its motion through space. The VLBA’s ability to detect this minuscule effect revealed the presence of the planet. Credit: Bill Saxton, NRAO/AUI/NSF Using the supersharp radio “vision” of the National […]

ANIMATION A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active and non-active, concludes that in the discs of the former the rotational motion of the stars is of greater importance. This study, just accepted […]

The moon Io orbits Jupiter in this image from NASA’s Cassini spacecraft. Jupiter and Io appear deceptively close in this image, when in fact the moon is orbiting 217,000 miles from the gas giant planet.

This artist’s illustration of Supernova 1987A shows the dusty inner regions of the exploded star’s remnants (red), in which a neutron star might be hiding. This inner region is contrasted with the outer shell (blue), where the energy from the supernova is colliding (green) with the envelope of gas ejected […]

The South Pole Telescope at the US Amundsen-Scott South Pole Station, with a bright aurora in July 2020. Credit: Geoff Chen Stars viewed from a place called Dome A in Antarctica can finally be seen without their twinkle – which means in much greater detail. Have you ever wondered why […]

HSC J1631+4426 broke the record for the lowest oxygen abundance. Credit: NAOJ/Kojima et al. Breaking the lowest oxygen abundance record. New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% […]
