new insights into how eruptions occur on the sun

New insights into how eruptions occur on the Sun

Scientists have gained new insights into how eruptions occur on the Sun and, through 3-D computer simulation, identified a universal process that explains eruptions of every size, from tapered jets to massive explosions of solar material and energy. In a new study...

new data shows heliosphere is nearly round and symmetrical

New data show heliosphere is nearly round and symmetrical

New data covering an entire 11-year solar activity cycle suggest that Sun and planets in our solar system are surrounded by a giant, spherical system of magnetic field from the Sun, calling into question the current view of the solar magnetic fields trailing behind...

Scientific evidence of a 'higher' state of consciousness found

Authors of a new study led by the University of Sussex claim they have found scientific evidence of a 'higher' state of consciousness. Neuroscientists observed a sustained increase in neural signal diversity - a measure of the complexity of brain activity -...

Slims River disappears in 4 days as glacier retreats

A retreat of the massive Kaskawulsh Glacier in northern Canada has caused the Slims River to change its course and join the Kaskawulsh River on its way toward to the Gulf of Alaska. It is the first known case of what is known as 'river piracy' in modern...

telescope image shows star formation can be a violent and explosive process

Telescope image shows star formation can be a violent and explosive process

Stellar explosions are most often associated with supernovae, the spectacular deaths of stars. But new ALMA observations provide insights into explosions at the other end of the stellar life cycle, star birth. Astronomers captured these dramatic images as they...

California droughts and floods linked to distinctive atmospheric waves

In a recent study, scientists at the National Center for Atmospheric Research (NCAR) found that the persistent high-pressure ridge off the west coast of North America that blocked storms from coming onshore during the winters of 2013-14 and 2014-15 was associated...

Discovery offers a way to predict solar flares

A new study led by a scientist at the National Center for Atmospheric Research (NCAR) has found that the same kind of large-scale planetary waves that meander through Earth's atmosphere driving our weather may also exist on our star and drive space weather. The...

Kaikoura earthquake, the most complex in modern history

In November 2016, a massive 7.8-magnitude earthquake hit New Zealand, causing significant damage and between 80 000 - 100 000 landslides. Now, an international team of scientists says the quake was so complex and unusual that it is likely to change how scientists...

Atmospheric supersonic plasma jets discovered

Supersonic plasma jets discovered

Scientists analyzing data obtained by Swarm trio of satellites have discovered supersonic plasma jets high up in our atmosphere that can push temperatures up to almost 10 000 °C (18 000 °F). The discovery was presented at this week’s Swarm Science...

mapping space dust in 3d

3-D map of space dust

A new study led by Edward F. Schlafly is providing a detailed, 3-D look at dust on a scale spanning thousands of light-years in our Milky Way galaxy. This dust map is of critical importance for the Dark Energy Spectroscopic Instrument (DESI), a Berkeley Lab-led...

Calbuco's eruption expanded ozone hole to record size

A new study argues that eruption of the Chilean volcano Calbuco on April 22, 2015 stretched the Antarctic Ozone Hole, the thinnest portion of the ozone shell that shields Earth from harmful radiation, to a record size nearly as large as Africa. It did so by ejecting...
