This artist’s impression shows the planet K2-18b, it’s host star and an accompanying planet in this system. K2-18b is now the only super-Earth exoplanet known to host both water and temperatures that could support life. UCL researchers used archive data from 2016 and 2017 captured by the NASA/ESA Hubble Space Telescope and developed open-source algorithms to analyse the starlight filtered through K2-18b’s atmosphere. The results revealed the molecular signature of water vapour, also indicating the presence of hydrogen and helium in the planet’s atmosphere.

First Water Detected on Planet in the Habitable Zone

The first successful atmospheric detection of an exoplanet orbiting in its star’s habitable zone, at a distance where water can exist in liquid form.
This illustration demonstrates the two ways that blue stragglers in star clusters form. The illustration on the left shows the collision model where two low-mass stars in an overcrowded environment experience a head-on collision, combining their fuel and mass to form a single hot star. The illustration on the right depicts the "vampire" model consisting of a pair of stars that undergo a transformation, with the lower-mass star draining its larger-mass companion of the hydrogen that fuels its rebirth.

Hubble Explores the Formation and Evolution of Star Clusters in the Large Magellanic Cloud

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations...

Hubble snapped a stunning image of cosmic fireworks at Eta Carinae

The Hubble Space Telescope recently captured a spectacular image of the galaxy’s largest ongoing stellar “fireworks” which reveals new details of a cosmic explosion....
While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from the NASA/ESA Hubble Space Telescope. This image is from the SPHERE/ZIMPOL observations of R Aquarii, and shows the binary star itself, as well as the jets of material spewing from the stellar couple. Credit: ESO/Schmid et al.

These Hubble Space Telescope images showcase two of the 19 galaxies analyzed in a project to improve the precision of the universe's expansion rate, a value known as the Hubble constant. The color-composite images show NGC 3972 (left) and NGC 1015 (right), located 65 million light-years and 118 million light-years, respectively, from Earth. The yellow circles in each galaxy represent the locations of pulsating stars called Cepheid variables

Fresh evidence for new Physics in the universe

By using NASA's Hubble Space Telescope, astronomers have precisely measured the expansion rate of the universe since it was first calculated nearly a century ago....
