Astronomy's dirty window to space: A detailed map of dust in the Milky Way
When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it appears? Or does the star merely look reddish, since its light has had to travel through a cloud of ...

Astronomers discover new supergiant fast X-ray transient, expanding rare class
Italian astronomers report the detection of a new X-ray binary (XRB), which has received the designation 4XMM J181330.1-17511 (J1813 for short). The newfound object represents the rare subclass of XRBs known as supergiant ...
Researchers develop glass sensors for the Einstein Telescope
From 2035, the Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For the telescope, researchers from Jena have manufactured highly sensitive sensors made entirely of glass for the first ...

Black holes spew out powerful jets that span millions of light-years. We're trying to understand their whole life cycle
There is a supermassive black hole at the center of nearly every big galaxy—including ours, the Milky Way (it's called Sagittarius A*). Supermassive black holes are the densest objects in the universe, with masses reaching ...

Observations of a nearby pulsar wind nebula reveal a radio jet feature with a helical magnetic field inside
Using the Australia Telescope Compact Array (ATCA), astronomers have performed high-resolution observations of a nearby pulsar wind nebula in the supernova remnant G11.2−0.3. Results of the observational campaign, published ...
White dwarf and red dwarf duo emit radio pulses every two hours
An international team of astronomers led by scientists from the Netherlands has shown that a white dwarf and a red dwarf orbiting each other every two hours are emitting radio pulses. Thanks to observations with several telescopes, ...

Supernova simulations show that low-mass star in binary system J0453+1559 could be a neutron star
In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly magnetized rapidly rotating, light-emitting neutron star) and a so-called companion star. The companion ...
Black hole X-ray binary SLX 1746–331 shows unusual outburst pattern
