A type of Martian aurora first identified by NASA’s MAVEN spacecraft in 2016 is actually the most common form occurring on the Red Planet, according to new results from the mission. The Martian aurora is known as a proton aurora and can help scientists track water loss from Mars’ atmosphere. On Earth, auroras are commonly seen ...
A question that has long puzzled scientists is how our Milky Way galaxy, which has an elegant spiral shape with long arms, took this form. Universities Space Research Association today announced that new observations of another galaxy are shedding light on how spiral-shaped galaxies like our own get their iconic shape. According to research from the Stratospheric ...
Shortly after NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission’s science team revealed that the asteroid could be active, or consistently discharging particles into space. The ongoing examination of Bennu — and its sample that will eventually be returned to Earth — could potentially shed light on why this intriguing ...
Scientists have improved a computer program that helps simulate the behavior of photons when interacting with hydrogen spilled in intergalactic space. The results have been published in the scientific journal Monthly Notices of the Royal Astronomical Society. Andrey Savelyev, associate professor of the Institute of Physical and Mathematical Sciences and Information Technologies of the IKBFU and ...
China recently launched two navigation satellites into space. While the mission was successful, it ended up sending booster segments crashing back to Earth. The two satellites are the 50th and 51st components of the GNS (global navigation satellite) system named the “BeiDou constellation” that China aims to complete by next year. Debris risk The satellites were ...
A Queen’s University Belfast scientist has led an international team to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface. The findings could help to solve the mystery of how the corona of the Sun maintains its multi-million-degree temperatures. For more than 60 years, observations of ...
The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialized telescopes, two international teams have registered the highest energy gamma-ray bursts ever measured from so-called gamma-ray bursts, reaching about 100 billion times as much energy as visible light. The scientists of the H.E.S.S. and MAGIC telescopes present their observations ...
A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the galaxy in which we live — the Milky Way. The image from the Murchison Widefield Array (MWA) telescope shows what our galaxy would look like if human eyes could see radio waves. The Galactic Center of the ...
NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station detected a sudden spike of X-rays at about 10:04 p.m. EDT on August 20. The burst was caused by a massive thermonuclear flash on the surface of a pulsar, the crushed remains of a star that long ago exploded as a supernova. The X-ray burst, ...
Black holes are an important part of how astrophysicists make sense of the universe — so important that scientists have been trying to build a census of all the black holes in the Milky Way galaxy. But new research shows that their search might have been missing an entire class of black holes that they ...
