Researchers Measure the Delay Between the X-Rays and the Visible Light of a Black Hole Jet
Nothing can emerge from a black hole. Yet, in nature, we find ultra-powerful jets of energy that shoot out from the immediate vicinities of growing…

A study led by a researcher at the IAC and published today in Nature Astronomy points to the role of the magnetic field as responsible…
At the center of our galaxy, in the immediate vicinity of its supermassive black hole, is a region wracked by powerful tidal forces and bathed…
Since astronomers first measured the size of an extrasolar planet seventeen years ago, they have struggled to answer the question: how did the largest planets…
“I believe the Big Bang never happened,” said Juliano César Silva Neves, a physicist at the University of Campinas’s Mathematics, Statistics & Scientific Computation Institute…
This artist’s rendering shows the tidal disruption event named ASASSN-14li, where a star wandering too close to a 3-million-solar-mass black hole was torn apart. The…
Astronomers used data from Hubble Space Telescope and ESA’s Gaia satellite to directly measure the 3D motions of individual stars in a nearby galaxy, achieving…
NASA’s Hubble Space Telescope peers into the distant Universe to reveal a galaxy cluster called Abell 2537. Galaxy clusters such as this one contain thousands…
Equipped with Newton’s law of universal gravitation (published in Principia 330 years ago) and powerful computational resources (used to apply the law to more than…
NASA’s Infrared Telescope Facility, or IRTF, gave comet 45P a thorough astronomical checkup as it zipped past Earth early in 2017. The results help fill…
Seasonal dark streaks on Mars that previously were described as possible signs of flowing water have steep slopes that are better matched to dry flow…
This image is from Cassini spacecraft’s final observation of Saturn’s icy moon Rhea (949 miles or 1,527 kilometers across) on May 2, 2017. The spacecraft…
A new study uses a combination of glacial morphology and remote sensing measurement to explore the role of ice in shaping Martian landslides. How good…
New research shows that the recently reported unexpected behavior on Saturn’s largest moon Titan is due to its unique atmospheric chemistry. Titan’s polar atmosphere recently…
The Earth’s Moon had a rough start in life. Formed from a chunk of the Earth that was lopped off during a planetary collision, it…
Astronomers reveal that asteroid ‘Oumuamua was traveling through interstellar space for millions of years before its chance encounter with our star system. For the first…
The vault-like, 40-foot (12-feet) diameter, 40-ton door of Chamber A at NASA’s Johnson Space Center in Houston was unsealed on November 18, signaling the end…
This Hubble image reveals the Cosmic Snake, a distant galaxy peppered with clumpy regions of intense star formation that appear warped by the effect of…
