Astronomers Uncover New Clues to the Star that Wouldn't Die

2 Aug 2018 at 12:00pm

It takes more than a massive outburst to destroy the mammoth star Eta Carinae, one of the brightest known stars in the Milky Way galaxy. About 170 years ago, Eta Carinae erupted, unleashing almost as much energy as a standard supernova explosion.

Yet that powerful blast wasn’t enough to oblitera...

Saturn and Mars Team Up to Make Their Closest Approaches to Earth in 2018

26 Jul 2018 at 9:00am

As Saturn and Mars ventured close to Earth, Hubble captured their portraits in June and July 2018, respectively. The telescope photographed the planets near opposition, when the Sun, Earth and an outer planet are lined up, with Earth sitting in between the Sun and the outer planet. Around the tim...

Photo Release: New family photos of Mars and Saturn from Hubble

26 Jul 2018 at 9:00am
Mars and Saturn close to oppositionIn summer 2018 the planets Mars and Saturn are, one after the other, in opposition to Earth. During this event the planets are relatively close to Earth, allowing astronomers to observe them in greater detail. Hubble took advantage of this preferred configuration and imaged both planets to contin... Read more...

Hubble and Gaia Team Up to Fuel Cosmic Conundrum

12 Jul 2018 at 9:00am

Using the powerful Hubble and Gaia space telescopes, astronomers just took a big step toward finding the answer to the Hubble constant, one of the most important and long-sought numbers in all of cosmology. This number measures the rate at which the universe is expanding since the big bang, 13.8 ...

NASA's Webb Space Telescope to Inspect Atmospheres of Gas Giant Exoplanets

11 Jul 2018 at 9:00am

Thousands of exoplanets are known to orbit distant stars. Far fewer have had their atmospheres studied. The Webb telescope will bring new capabilities for determining atmospheric compositions, temperatures, and structures. Some of Webb’s earliest observations will focus on gas giants, whose puffy...

Science Release: Hubble sees `Oumuamua getting a boost

27 Jun 2018 at 12:00pm
Artist’s impression of the interstellar asteroid `Oumuamua`Oumuamua, the first interstellar object discovered in the Solar System, is moving away from the Sun faster than expected. This anomalous behaviour was detected using the NASA/ESA Hubble Space Telescope in cooperation with ground-based telescopes. The new results suggest that `Oumuamua is most li... Read more...

Science Release: Hubble proves Einstein correct on galactic scales

21 Jun 2018 at 1:00pm
Image of ESO 325-G004An international team of astronomers using the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope has made the most precise test of general relativity yet outside our Milky Way. The nearby galaxy ESO 325-G004 acts as a strong gravitational lens, distortin... Read more...

Photo Release: Cosmic collision lights up the darkness

31 May 2018 at 9:00am
Peculiar galaxy NGC 3256Though it resembles a peaceful rose swirling in the darkness of the cosmos, NGC 3256 is actually the site of a violent clash. This distorted galaxy is the relic of a collision between two spiral galaxies, estimated to have occurred 500 million years ago. Today it is still reeling in the aftermath... Read more...

Astronomers Release Most Complete Ultraviolet-Light Survey of Nearby Galaxies

17 May 2018 at 12:00pm

Much of the light in the universe comes from stars, and yet, star formation is still a vexing question in astronomy.

To piece together a more complete picture of star birth, astronomers have used the Hubble Space Telescope to look at star formation among galaxies in our own cosmic back yard. The...

Photo Release: Hubble shows the local Universe in ultraviolet

17 May 2018 at 12:00pm
The glowing spiral arms of NGC 6744Using the unparalleled sharpness and ultraviolet observational capabilities of the NASA/ESA Hubble Space Telescope, an international team of astronomers has created the most comprehensive high-resolution ultraviolet-light survey of star-forming galaxies in the local Universe. The catalogue contai... Read more...
