Science Release : Hubble measures the size of the nearest transiting Earth-sized planet

16 novembre

The NASA/ESA Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighbouring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have.

Photo Release : Webb, Hubble Combine to Create Most Colourful View of Universe

9 novembre

The NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope have united to study an expansive galaxy cluster known as MACS0416. The resulting panchromatic image combines visible and infrared light to assemble one of the most comprehensive views of the Universe ever (…)

Science Release : Hubble finds bizarre explosion in unexpected place

5 octobre

A very rare, strange burst of extraordinarily bright light in the universe just got even stranger – thanks to the eagle-eye of the NASA/ESA Hubble Space Telescope. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto the scene where it wasn’t expected to be (…)

Photo Release : Hubble dispels dust to see a glittering globular cluster

7 septembre

The glittering globular cluster Terzan 12 — a vast, tightly bound collection of stars — fills the frame of this image from the NASA/ESA Hubble Space Telescope. The location of this globular cluster, deep in the Milky Way galaxy in the constellation Sagittarius, means that it is shrouded in gas (…)

Photo Release : Hubble sees boulders escaping from asteroid Dimorphos

20 juillet

Astronomers using the NASA/ESA/ Hubble Space Telescope’s extraordinary sensitivity have discovered a swarm of boulders that were possibly shaken off the asteroid Dimorphos when NASA deliberately slammed the half-tonne DART impactor spacecraft into Dimorphos at approximately 22 500 kilometres (…)

Science Release : Hubble hunts for intermediate-sized black hole close to home

23 mai

Astronomers using the NASA/ESA Hubble Space Telescope have come up with what they say is some of their best evidence yet for the presence of a rare class of intermediate-sized black holes, having found a strong candidate lurking at the heart of the closest globular star cluster to Earth, (…)

Science Release : Hubble follows shadow play around planet-forming disc

4 mai

In 2017 astronomers reported discovering a shadow sweeping across the face of a vast pancake-shaped disc of gas and dust surrounding the red dwarf star TW Hydrae. The shadow isn’t from a planet, but from an inner disc slightly inclined relative to the much larger outer disc — causing it to (…)

Photo Release : Hubble celebrates its 33rd anniversary with a peek into a nearby star-forming region

20 avril

Astronomers are celebrating the NASA/ESA Hubble Space Telescope’s 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. The nebula is in the Perseus molecular cloud, and is located approximately 960 light-years away.

Photo Release : Hubble monitors changing weather and seasons on Jupiter and Uranus

23 mars

Ever since its launch in 1990, the NASA/ESA Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the ever-changing atmospheres of the largely gaseous outer planets. And it’s an unblinking eye that allows Hubble’s sharpness and sensitivity to monitor a (…)

Photo Release : Hubble captures movie of DART asteroid impact debris

1er mars

The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our (…)
