Astronomers from Italy and Spain have observed a binary system known as HD 189733, using ESA's XMM-Newton satellite. Results of the observational campaign, published January 28 on arXiv.org, deliver essential information ...
We've all experienced the principle of feedback—for example, when we use a thermostat in conjunction with a heating system to regulate indoor temperature. The thermostat measures the current temperature, compares it with ...
