Three planets found around dust-shrouded star

Two teams of astronomers using the Atacama Large Millimetre/submillimetre Array – ALMA – have spotted three newly formed planets orbiting an infant star in its dusty protoplanetary disc. It is the first detection of its kind. Confirming the presence of young worlds in such dust-shrouded discs is difficult, but the teams, working independently, used a novel technique to spot the othe...

The Sky This Week

Tuesday, June 12 Mars rises shortly before midnight local daylight time and climbs nearly 30° high in the south by the time morning twilight commences. Although it is still a month and a half away from its late July opposition, the Red Planet appears noticeably brighter than it did just a week ago. Shining at magnitude –1.6, it is the third-brightest point of light in the night sky...

Astronomers find source of stars' mysterious microwaves

Mysterious streams of microwaves that come from far across the galaxy have been traced to immense clouds of spinning diamonds that swirl around newly-born stars. Astronomers have been stumped by the strange waves since they were first spotted more than 20 years ago, but now appear to have solved the puzzle after training US and Australian telescopes on rings of dust that circle stars about 500...

Even if everybody warned me about Massachusetts winters — and even if I’ve lived in northern climes in the past — nothing quite prepared me for the nor’easters slingshotting one after the other into Cambridge, dumping more snow in one go than I’ve ever seen...

Observe Changes on Mars

Ever since mid-2017, Earth has been steadily closing in on Mars. The approach culminates July 27th in opposition. As the closest rocky planet to Earth whose surface is visible in modest telescopes, Mars easily garners the most attention of all the inner planets. The Red Planet often reveals subtle changes from year to year that stand out to the patient observer. But occasionally, big cha...

This Week’s Sky at a Glance, June 15 – 23

Friday, June 15 As twilight fades after sunset, look very low in the west-northwest for the thin crescent Moon under Venus, as shown here. It's almost summer. But as twilight fades, look very low in the north-northwest for wintry Capella very out of season. The farther north you are, the higher it will appear. You may need binoculars. If you're as far north as Portland Oregon and Portland Maine,...
