No earlier than Aug. 6, 2018, a United Launch Alliance Delta IV Heavy will thunder to space carrying the car-sized spacecraft, which will study the Sun closer than any human-made object ever has.
Astronomy & Astrophysics publishes the predictions of the passages of foreground stars in front of background stars. A team of astronomers, using ultra-precise measurements from the Gaia satellite, have accurately forecast two passages in the next months. Each event will produce shifts in the background star's position due to the deflection of light by gravity, and will allow the measurement of the mass of the foreground star, which is extremely difficult to determine by other means.
This summer, NASA's Parker Solar Probe will launch to travel closer to the Sun, deeper into the solar atmosphere, than any mission before it. Cutting-edge technology and engineering will help it beat the heat.
An international team of researchers, led by Professor Shoji Torii of Waseda University, succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET). Observations by CALET are expected to reveal the mysteries of cosmic-rays and nature of dark matter in the future.
Using advanced algorithms and data-cleaning techniques, scientists discovered never-before-detected, fine-grained structures in the outer corona -- the Sun's million-degree atmosphere -- by analyzing images taken by NASA's STEREO spacecraft.
A Southwest Research Institute-led team discovered never-before-detected, fine-grained structures in the Sun's outer atmosphere, or corona. The team imaged this critical region in detail using sophisticated software techniques and longer exposures from the COR-2 camera on board NASA's Solar and Terrestrial Relations Observatory-A (STEREO-A).
MIT analysis of X-ray data suggests the first observations of a star swallowing a planet, and may also explain the star's mysterious dimming.
With its increased reliability and its data on the polarisation of relic radiation, the Planck mission corroborates the standard cosmological model with unrivalled precision for these parameters, even if some anomalies still remain. For this work the Planck consortium called upon some three hundred researchers, in particular from CNRS, CNES (the French national space agency), CEA (the French Alternative Energies and Atomic Energy Commission) and several universities in France.
ESO's Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography -- and has captured remarkably sharp test images of the planet Neptune and other objects. The MUSE instrument working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope.
An international team of scientists, including researchers at the South Dakota School of Mines & Technology, have found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth.
