Bow Shock Leads the Way for a Speeding Hot Jupiter
A bow shock has been detected ahead of transiting exoplanet HD 189733b, providing a potential indicator of the remarkably strong magnetic field of the planet.

A new study suggests we may be over-predicting the rate of galaxy mergers — and the gravitational wave background — by counting X-shaped radio sources.
Recent models provide an explanation for the “early activity” unexpectedly emerging from the neck of comet 67P.
Observations of starbursts in low-metallicity galaxies have provided long-awaited evidence supporting predictions of how stars formed throughout cosmic history.
A recent study has found that the transitional disk DoAr 44 contains water vapor in its inner regions.
Neptune’s unusual migration in the early years of our solar system might have created features we now observe in the Kuiper Belt.
Chandra X-ray images of RCW 103 provide an updated picture of what’s happening in this puzzling supernova remnant.
When an unfortunate star passes too close to a dormant supermassive black hole it gets torn apart by tidal forces, feeding the black hole for a short time. A recent study of the streams of stellar material in these events explains why we might be missing many of them.
At the end of last year, the Sun’s large-scale magnetic field suddenly strengthened, reaching its highest value in over two decades. Here, researchers explain why this happened and what it predicts for the next solar cycle.
Which type of galaxy is most likely to host complex life in the universe? A team of researchers from the UK has the answer.
The very first exoplanets ever confirmed were found around a pulsar — but since then we’ve only found one other similar case. In this study, a team of researchers tries to figure out why.
This study suggests that the stars in the central parsec of our galaxy are not a single, roughly solar-metallicity population, as previously thought.
