Sunspots from Feb 2017 vs March 2017

Our Sun's been using facial scrub: No spots for two weeks

NASA's Solar Dynamics Observatory has spotted nothing for the last two weeks, which is unusual.

Blocking out the Sun won't fix climate change – but it could buy us time

The Paris climate talks hope to set out how we can reduce the amount of carbon we’re pumping into the atmosphere. But emissions cuts alone may not be enough. Atmospheric CO2 is the blanket that keeps our planet warm and any further emissions will mean more global warming. Observations in recent years show that warming is …

Larry Ellison on stage at the launch of Oracle's X5 engineered systems range

The firm that swallowed the Sun: Is Oracle happy as Larry with hardware and systems?

Oracle-Sun anniversary One Sun swallow doesn’t make a hardware summer, and while it certainly hasn’t for Oracle, it is far from being in a hardware winter for the firm. Oracle's gulp of Sun Microsystems on 27 January 2010 – five years ago today – has resulted in a generally flagging Sun hardware product business and the growing Engineered System …
