Dust particles in space are mixed with ice, as a research team from Friedrich Schiller University Jena and the Max Planck Institute for Astronomy has now proven in lab experiments. Furthermore, they observed "trapped water", which should thus also exist in space.
Insight-HXMT, China's first space X-ray astronomical satellite, has discovered a low-frequency quasi-periodic oscillation (QPO) above 200 kiloelectron volts (keV) in a black hole binary, making it the highest energy low-frequency QPO ever found. The scientists also found that the QPO originated from the precession of a relativistic jet near the event horizon of the black hole.
A new study has tracked the long-term impact of early seed funding obtained from the National Science Foundation on many key advances in astronomy over the past three decades.
In a paper published today in Nature Astronomy, researchers report the first ever clear images of nanojets -- bright thin lights that travel perpendicular to the magnetic structures in the solar atmosphere, called the corona -- in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares.
Scientists at MIT and elsewhere have discovered a "pi Earth" -- an Earth-sized planet that zips around its star every 3.14 days, in an orbit reminiscent of the universal mathematics constant.
A black hole is an exotic cosmic object, from within which nothing, not even light, can escape. Definitive proof of the existence of such objects is a holy grail of physics and astronomy. An international team of astrophysicists, consisting of Mr. Srimanta Banerjee, Professor Marat Gilfanov, Professor Sudip Bhattacharyya and Professor Rashid Sunyaev, has found by far the strongest steady signature of stellar-mass black holes to date, from the cosmic X-rays observed with a satellite.
Using the VLBA, astronomers have made the first direct geometric measurement of the distance to a magnetar. This precision measurement to one of the most magnetic objects in the Universe could help scientists determine if such objects are responsible for generating the mysterious Fast Radio Bursts.
Hubble's sharp view is giving researchers an updated weather report on the monster planet's turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous Great Red Spot region gearing up to change color -- again.
When stars like our sun die, all that remains is an exposed core - a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.
With almost two decades of mid-infrared imaging from the largest observatories around the world including the Subaru Telescope, a team of astronomers was able to capture the spiral motion of newly formed dust streaming from the massive and evolved binary star system WR112. The study reveals the motion of the dusty outflow from the system and identifies WR112 as a highly efficient dust factory that produces an entire Earth mass of dust every year.
