Turbulent solar wind originates in the sun's corona, study shows
Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic ...

Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. ...

Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using the NASA/ESA Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to erupt along its ...

The universe is smoother than the standard model of cosmology suggests. So is the theory broken?
Given how unfathomably large the universe is, it is perhaps understandable that we haven't yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists ...

Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time ...

How special is the Milky Way galaxy? Survey team releases new findings
Is our home galaxy, the Milky Way galaxy, a special place? A team of scientists started a journey to answer this question more than a decade ago. Commenced in 2013, the Satellites Around Galactic Analogs (SAGA) Survey studies ...

How a nearby supernova left its mark on Earth life
When a massive star explodes as a supernova, it does more than release an extraordinary amount of energy. Supernovae explosions are responsible for creating some of the heavy elements, including iron, which is blasted out ...

Study inspects unusual behavior of an X-ray binary
Astronomers from the National Central University in Taiwan have investigated an unusual superorbital period variation of an X-ray binary known as 4U 1820-30. Results of the study, published September 13 on the preprint server ...
A new catalog charts the evolution of the universe over time
An atlas doesn't seem to be an essential item in cars these days, but think about them and most people will think about distances. An atlas of the stars not only covers distances but must also take into account time too. ...

Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported ...

Quantized redshift and challenges to Big Bang hypothesis
A Doppler shift is defined as a change of frequency of light or sound when an object is moving toward or away from an observer. Edwin Hubble observed in 1929 that galaxies appear on average to be moving away from us (see ...
High-resolution images of the sun show how flares impact the solar atmosphere
Solar flares are a fascinating thing and have a profound effect on what astronomers refer to as "space weather." These events vary with the sun's 11-year solar cycle, releasing immense amounts of radiation across the electromagnetic ...
