Gravitational lensing provides a new measurement of the expansion of the universe
Amid ongoing uncertainty around the value of the Hubble Constant, uncertainty largely created by issues around measuring distances to objects in the galaxy, scientists who used a new distance technique have derived a different Hubble value, one “somewhat higher than…
Hubble reveals latest portrait of Saturn
The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 observed Saturn on 20 June 2019 as the planet made its closest approach to Earth this year, at approximately 1.36 billion kilometres away. Since the Hubble Space Telescope was launched, its…
Saturn’s rings shine in Hubble’s latest portrait
Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth. These images, however, are more than just beauty shots. They…
Innovative model created for NASA to predict vitamin levels in spaceflight food
Mathematical tool from UMass Amherst researchers will ensure proper nutrition for astronauts on long

Gravitational wave ‘tones’ detected following the merger of two black holes confirm the decades-old
The rare molecule weighing in on the birth of planets
Astronomers using one of the most advanced radio telescopes have discovered a rare molecule in the dust and gas disc around a young star – and it may provide an answer to one of the conundrums facing astronomers. The star,…

Space dragons: Researchers observe energy consumption in quasars
Quasars are the Universe’s brightest beacons; shining with magnitudes more luminosity than entire galaxies and the stars they contain. In the center of this light, at the heart of a quasar, researchers think, is an all-consuming black hole. Researchers, for…

European funding to learn more about the evolution of the Universe
Dr Florian Beutler from the University of Portsmouth’s Institute of Cosmology and Gravitation has been awarded a European Research Council grant to help further our understanding of the evolution of the Universe. The funding helps individual scientists and scholars to…
Melatonin is a potential drug for the prevention of bone loss during space flight
[Background] For proper and healthy metabolism of bone, appropriate stimuli are necessary. In outer space with microgravity, calcium is lost from bone and bone mass is reduced. Measurement of the bone density of astronauts before and after a long stay…
Study reveals ‘radical’ wrinkle in forming complex carbon molecules in space
Unique experiments at Berkeley Lab’s Advanced Light Source shine a light on a new pathway for carbon
Study tests performance of electric solid propellant
Electric solid propellants are being explored for use in dual-mode rocket engines because they aren’t susceptible to ignite from a spark or flame and can be turned on and off electrically. Researchers from the University of Illinois at Urbana-Champaign, Missouri…

Busy older stars outpace stellar youngsters, new study shows
The oldest stars in our Galaxy are also the busiest, moving more rapidly than their younger counterparts in and out of the disk of the Milky Way, according to new analysis carried out at the University of Birmingham. The findings…
Chipping away at how ice forms could keep windshields, power lines ice-free
SAN DIEGO, Aug. 27, 2019 — How does ice form? Surprisingly, science hasn’t fully answered that question. Differences in ice formation on various surfaces still aren’t well understood, but researchers today will explain their finding that the arrangements that surface…

New study suggests that the nightsides of hot Jupiters share clouds made of minerals
Streaks in aurora found to map features in earth’s radiation environment
A special kind of streaked aurora has been found to track disturbances in near-Earth space from the ground. Known as structured diffuse aurora, it was recently discovered, with the help of NASA spacecraft and instruments, that these faint lights in…

Astrophysicists link brightening of pulsar wind nebula to pulsar spin-down rate transition
Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU…

Images from the surface of asteroid Ryugu yield clues to its composition
New images taken by a lander on the surface of the near-Earth asteroid Ryugu have yielded clues into the composition and origins of its rocks, which bear strong similarities to primitive meteorites called carbonaceous chondrites. The findings from Ralf Jaumann…
Moon glows brighter than sun in images from NASA’s Fermi
If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That’s how NASA’s Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade. Gamma-ray observations are not sensitive…
