17:54 Phys.orgImage: Hubble peers at galactic cherry blossoms

The galaxy NGC 1156 resembles a delicate cherry blossom tree flowering in springtime in this Hubble image. The many bright "blooms" within the galaxy are in fact stellar nurseries—regions where new stars are springing to life. Energetic light emitted by newborn stars in these regions streams outwards and encounters nearby pockets of hydrogen gas, causing the gas to glow with a characteristic pink hue.

Although it makes up about 85 percent of all matter in the universe, dark matter is frustratingly hard to pin down. In order to figure out what it is, much of the search is about ruling out what dark matter isn't, and now physicists at Stanford and the SLAC National Accelerator Laboratory have narrowed it down further. Using observations of galaxies orbiting the Milky Way, the team found that dark matter is likely lighter than previously thought – and interacts even less with normal matter.

The role of an excited black hole in the death of an exotic 'jellyfish' galaxy will be presented today (3 July) by Callum Bellhouse of the University of Birmingham at the RAS National Astronomy Meeting in Lancaster. The supermassive black hole at the centre of jellyfish galaxy JO201 is stripping away gas and throwing it out into space, accelerating suppression of star formation and effectively 'killing' the galaxy.

Over time, scientists have developed different theories to explain exactly what the mysterious dark matter might be made of. Researchers have now found a way of detecting axions with the help of the Cosmic Axion Spin Precession Experiment (CASPEr) program. The basic assumption is that dark matter can influence the spin of nuclei, hence providing researchers with a way of tracking it down.

20:59 Phys.orgFast radio burst pinpointed to distant galaxy

Fast radio bursts (FRBs) are among the most enigmatic and powerful events in the cosmos. Around 80 of these events—intensely bright millisecond-long bursts of radio waves coming from beyond our galaxy—have been witnessed so far, but their causes remain unknown.

Matter surrounds us day and night in all its forms—trees, houses, furniture, and even the air we breathe. But, according to physicists, the visible matter familiar to us may only account for approximately 20 percent of all material in the universe. According to the current theory, as much as 80 percent may be dark matter. This claim is based on several observations, one of which is that stars and galaxies rotate much faster than they would if there were only 'normal' matter present in the universe.
