    Using an innovative method, the mass of a pulsar can be constrained using the maximum ‘glitch’ in the star’s rotational frequency: the bigger the glitch, the lower the mass. This method is used to estimate the mass of all observed glitchers.

    The origin of Galactic positrons that produce gamma ray emission when annihilated is still debated. Mergers of two white dwarfs are likely to be the main source of these positrons. Such mergers produce sub-luminous, thermonuclear supernovae.

    Woken from the deep sleep of a hibernated spacecraft, NEOWISE now monitors the population of near-Earth objects for science and Earth protection purposes, explains Principal Investigator Amy Mainzer.

    Scientists are beyond concerned. We are angry about the cuts to fundamental research and the decline in scientific literacy among politicians. But protesting isn't everything — we also need to adapt to change and engage with the public.

Cometary catastrophes

Rosetta’s cameras captured the collapse of a cliff on the nucleus of comet 67P in near real time, unambiguously connecting it with an outburst of cometary activity.  This landslide also exposed the fresh icy material of the interior of the comet, formed in the cold part of our Solar System roughly 4.5 billion years ago.

See Pajola et al. 1, 92 (2017).
