A new model for dark matter
Dark matter remains one of the greatest mysteries of modern physics. It is clear that it must exist, because without dark matter, for example, the motion of galaxies cannot be explained. But it has never been possible to detect dark matter in an experiment.
Currently, there are many proposals for new experiments: They aim to detect dark matter directly via its scattering from the constitue A paradigm shift in our understanding of a well-known astrophysical phenomenon
Matter outflows in the form of jets are observed in astronomical systems at fast, medium and slow speeds. The fastest jets are highly relativistic, namely travel very close to the speed of light. The origin, as well as many properties of the jets, is uncertain. One of the puzzles, that jet velocities seem to have a bi-modal distribution - some very fast and others slow, with a gap in velocities DARPA selects Aurora Flight Sciences for Phase 2 of Active Flow Control X-Plane
DARPA has selected Aurora Flight Sciences to move into the detailed design phase of the Control of Revolutionary Aircraft with Novel Effectors (CRANE) program. This follows successful completion of the project's Phase 1 preliminary design, which resulted in an innovative testbed aircraft that used active flow control (AFC) to generate control forces in a wind tunnel test.

Today's glass-based ground and space telescopes are limited in their ability to provide resolved imagery of objects in geostationary orbit, 36,000 kilometers above earth. The cost to build and maintain complex optics large enough to effectively track items at that distance is prohibitive. Another key limitation of space-based telescopes is the escalating probability of in-orbit debris causing da Milky Way found to be more unique than previously thought
Is the Milky Way special, or, at least, is it in a special place in the Universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows that the Milky Way is too big for its "cosmological wall", something yet to be seen in other galaxies. The new research is published in Monthly Notices of the Royal Astronom Our Solar System is filled with asteroids that are particularly hard to destroy
A vast amount of rocks and other material are hurtling around our Solar System as asteroids and comets. If one of these came towards us, could we successfully prevent the collision between an asteroid and Earth?
Well, maybe. But there appears to be one type of asteroid that might be particularly hard to destroy.

Not all flashlights are created equal. Some are stronger, consume more power, or have features such as blinking or strobes. Some aren't even meant for humans, such as a new project that recently received funding from a NASA Institute for Advanced Concepts (NIAC) Phase I award. Designed by the Ultra Safe Nuclear Corporation (USNC), this flashlight doesn't emit visible light, but it does emit X-rays and gamma rays, and the researchers on the project think it could be useful for finding resources on the moon.
The key to this technology is a novel radioisotope that USNC developed that goes by the trade name EmberCore. It is a type of nuclear chargeable ceramic, similar to the radioisotopes contained in the radioisotope thermal generators used by Mars rovers such as Curiosity and Perseverance.
