Hurt (Caltech) The results are rolling in from Caltech's newest state-of-the-art sky-surveying camera, which began operations at the Palomar Observatory in March 2018. Called the Zwicky Transient…

Ramped up efforts needed to protect the world’s inland waters

At least 15% of the world's inland surface water areas are covered by protected areas, according to a new study from the JRC. This is close to the global target of 17% set out in Aichi Target 11 of the Strategic Plan for Biodiversity 2011-2020 of the Convention on Biological Diversity (CBD). However, surface water protection is very unevenly distributed globally, still falling well below…

Visualization of regions of electromagnetic wave-plasma interactions surrounding the Earth

[Background] It is known that in the space surrounding the Earth (the space up to the geostationary orbit altitude, called Geospace), there are natural trapped charged particles, Van Allen belts, that may affect commercial satellite services (meteorology, communication, GPS and others), and there is concern that astronauts would be exposed to these charged particles, for example in a manned mission to the moon. The high-energy…

The Milky Way in a twist

Our Milky Way galaxy's disk of stars is anything but stable and flat. Instead, it becomes increasingly 'warped' and twisted far away from the Milky Way's center, according to astronomers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC). From a great distance, our galaxy would look like a thin disk of stars that orbit once every few hundred million years around its central…

The Milky Way is warped

The first accurate 3D map of our galaxy reveals its true shape: warped and twisted. Astronomers from Macquarie University and the Chinese Academy of Sciences have used 1339 'standard' stars to map the real shape of our home galaxy in a paper published in Nature Astronomy today. They found the Milky Way's disc of stars becomes increasingly 'warped' and twisted the further away the stars…
