RAS congratulates Cassini-Huygens team on an amazing 17 years

(Royal Astronomical Society) Tomorrow (15 September) sees the final demise of the Cassini spacecraft, as it plunges into the atmosphere of Saturn, after 17 years of continuous discovery. The Royal Astronomical Society (RAS), the leading...Show More Summary

New supernova analysis reframes dark energy debate

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research published in the journal Monthly Notices of the Royal Astronomical Society. The new study—by a group at the University...Show More Summary

Kepler satellite discovers variability in the Seven Sisters

(Royal Astronomical Society) Dr. Tim White of the Stellar Astrophysics Centre at Aarhus University and his team of Danish and international astronomers have demonstrated a powerful new technique for observing stars such as the Pleiades star cluster, which are ordinarily far too bright to look at with high performance telescopes.

Spiral arms allow school children to weigh black holes

(Royal Astronomical Society) Astronomers from Swinburne University of Technology, Australia, and the University of Minnesota Duluth, USA, have provided a way for armchair astronomers, and even primary school children, to merely look at a spiral galaxy and estimate the mass of its hidden, central black hole.

Re-making planets after star-death

(Royal Astronomical Society) Astronomers Dr. Jane Greaves, of the University of Cardiff, and Dr. Wayne Holland, of the UK Astronomy Technology Centre in Edinburgh, may have found an answer to the 25-year-old mystery of how planets form in the aftermath of a supernova explosion. Show More Summary

Surprise methanol detection points to an evolving story of Enceladus's plumes

(Royal Astronomical Society) A serendipitous detection of the organic molecule methanol around an intriguing moon of Saturn suggests that material spewed from Enceladus undertakes a complex chemical journey once vented into space. This is the first time that a molecule from Enceladus has been detected with a ground-based telescope. Show More Summary

Musical sun reduces range of magnetic activity

(Royal Astronomical Society) A study of the sun using sound waves suggests that the layer in which the significant magnetic activity is located has grown thinner in recent years. Professor Yvonne Elsworth will present results at the National Astronomy Meeting at the University of Hull on Tuesday, July 4.

Under pressure -- Extreme atmosphere stripping may limit exoplanets' habitability

(Royal Astronomical Society) New models of massive stellar eruptions hint at an extra layer of complexity when considering whether an exoplanet may be habitable or not. Models developed for our own Sun have now been applied to cool stars...Show More Summary

National Astronomy Meeting 2017: Second media announcement

RAS funds five public engagement projects to mark 200th anniversary

(Royal Astronomical Society) Planet walks and planetaria in Galway, tactile stargazing for people with sight loss, adventures in space for girls, astronomy and geophysics for rehabilitation of prisoners, and a science trailer for Cornwall make up five new public engagement projects supported by more than £400,000 from the Royal Astronomical Society.

New survey hints at exotic origin for the Cold Spot

(Royal Astronomical Society) A supervoid is unlikely to explain a 'Cold Spot' in the cosmic microwave background, according to the results of a new survey, leaving room for exotic explanations like a collision between universes. TheShow More Summary

Alien Water Worlds --"Most Habitable Planets May Have Oceans Spanning 90% of Their Surface"

When it comes to exploring exoplanets, it may be wise to take a snorkel along. A new study, published in a paper in the journal Monthly Notices of the Royal Astronomical Society, has used a statistical model to predict that...      ...

Oceans galore: new study suggests most habitable planets may lack dry land

When it comes to exploring exoplanets, it may be wise to take a snorkel along. A new study, published in a paper in the journal Monthly Notices of the Royal Astronomical Society, has used a statistical model to predict that most habitable planets may be dominated by oceans spanning over 90% of their surface area.

Paintings, sunspots and frost fairs: Rethinking the Little Ice Age

(Royal Astronomical Society) The whole concept of the 'Little Ice Age' is 'misleading,' as the changes were small-scale, seasonal and insignificant compared with present-day global warming, a group of solar and climate scientists argue. The new work, led by Prof Mike Lockwood of the University of Reading, appears in a paper in Astronomy & Geophysics.

Astronomers to peer into a black hole for first time with new Event Horizon Telescope

Ever since first mentioned by Jon Michell in a letter to the Royal Society in 1783, black holes have captured the imagination of scientists, writers, filmmakers and other artists. Perhaps part of the allure is that these enigmatic objects have never actually been "seen". Show More Summary

RAS response to the US Executive Order banning entry from 7 countries

(Royal Astronomical Society) The Royal Astronomical Society (RAS) is greatly concerned by the Executive Order announced last week by US President Donald Trump, which prevents people from seven Middle Eastern and African countries from entering the United States.

A Dwarf Galaxy 10,000 Times Smaller Than Milky Way --"May Be a Portal to a New Physics"

Statistical analysis of mini-spiral galaxies shows an unexpected interaction between dark matter and ordinary matter. According to a study recently published in Monthly Notices of the Royal Astronomical Society, where the relationship is obvious and cannot be explained in a...        

Unexpected interaction between dark matter and ordinary matter in mini-spiral galaxies

Statistical analysis of mini-spiral galaxies shows an unexpected interaction between dark matter and ordinary matter. According to the SISSA study recently published in Monthly Notices of the Royal Astronomical Society, where the relationship...Show More Summary

Simulations suggest life on planet Proxima b might be possible if it has a thick atmosphere or strong magnetic field

(Phys.org)—Dimitra Atri, an astrobiologist with the Blue Marble Institute of Space Science, has published a paper in Monthly Notices of the Royal Astronomical Society outlining his work running simulations of planet Proxima b, an exoplanet circling the star Proxima Centauri, which could possibly support life.
