A team of super bright galaxies in the early universe

In 2015, Dr. David Sobral of Lancaster University led a team that found the first example of a spectacularly bright galaxy in the young universe named CR7 which may harbour first generation stars. Now, astronomers have identified a family of incredible galaxies that could shed further light on the transformation of the early universe known as the “epoch of reionisation.”

Astronomers detect double ‘peanut shell’ galaxies

Astronomers at Swinburne University of Technology, Melbourne, have discovered an unusually shaped structure in two nearby disc galaxies. The Swinburne team recently developed new imaging software, making it possible to observe the double “peanut shell shape” formed by the distribution of stars bulging from the centres of these galaxies.

Where to view the transit of Mercury on 9 May

With the transit of Mercury just two days away, interest in this comparatively rare event is growing fast. Given the favourable timing of this 7½-hour phenomenon for the UK, many will be able to view it at lunchtime or after work. If you don’t have suitably equipped telescope, join one of the many transit-viewing activities hosted by astronomical organisations nationwide.

Rare transit of Mercury to take place on 9 May

On Monday, 9 May there will be a rare transit of Mercury, when the innermost planet in our solar system will pass directly between the Earth and the Sun. The last time this happened was in 2006. With a properly filtered telescope and fine weather, the entire 7½-hour event can be seen from the British Isles.

Hubble unveils monster stars in the Tarantula Nebula

Astronomers using the unique ultraviolet capabilities of the NASA/ESA Hubble Space Telescope have identified nine monster stars with masses over 100 times the mass of the Sun in the star cluster R136, located in the Tarantula Nebula within the Large Magellanic Cloud. This makes it the largest sample of very massive stars identified to date.

Students map Milky Way with dwarf stars

Two astronomy students from Leiden University have mapped the entire Milky Way Galaxy in dwarf stars for the first time. They show that there are a total of 58 billion dwarf stars, of which seven percent reside in the outer regions of our galaxy. This result is the most comprehensive model ever for the distribution of these stars.

A lonely planet and its distant star

A team of astronomers in the UK, USA and Australia have found a planet, until now thought to be a free floating, in a huge, 900,000-year orbit around its star. Incredibly the object, designated as 2MASS J2126, is about 1 trillion (1 million million) kilometres from the star, or about 7,000 times the distance from the Earth to the Sun.
