We present the data release for Galaxy Zoo 2 (GZ2), a citizen science project with more than 16 million morphological classifications of 304 122 galaxies drawn from Sloan Digital Sky Survey (SDSS). Morphology is powerful probe quantifying galaxy's dynamical history; however, automatic morphology (either by computer analysis images or using other physical parameters as proxies) still have drawbacks when compared to visual inspection. The large number available in current surveys makes...
Abstract Camera traps can be used to address large-scale questions in community ecology by providing systematic data on an array of wide-ranging species. We deployed 225 camera across 1,125 km 2 Serengeti National Park, Tanzania, evaluate spatial and temporal inter-species dynamics.

We report the discovery of 29 promising (and 59 total) new lens candidates from Canada–France–Hawaii Telescope Legacy Survey (CFHTLS) based on about 11 million classifications performed by citizen scientists as part first Space Warps search. The goal blind search was to identify missed robots (the ringfinder galaxy scales and arcfinder group/cluster scales) which had been previously used mine CFHTLS for lenses. compare some properties samples detected these algorithms sample find them be...
Legacy data from natural history collections contain invaluable and irreplaceable information about biodiversity in the recent past, providing a baseline for detecting change forecasting future of on human-dominated planet. However, these are often not available formats that facilitate use synthesis. New approaches needed to enhance rates digitization quality improvement. Notes Nature provides one such novel approach by asking citizen scientists help with transcription tasks. The initial...
Planet Hunters is a new citizen science project, designed to engage the public in an exoplanet search using NASA Kepler release data. In first month after launch, users identified two planet candidates which survived our checks for false- positives. The follow-up effort included analysis of Keck HIRES spectra host stars, pixel centroid offsets data and adaptive optics imaging at NIRC2. Spectral synthesis modeling coupled with stellar evolutionary models yields density distribution, used...

We study dust and associated molecular gas in 352 nearby early-type galaxies (ETGs) with prominent lanes. 65% of these `dusty ETGs' (D-ETGs) are morphologically disturbed, suggesting a merger origin. This is consistent the D-ETGs residing lower density environments compared to controls drawn from general ETG population. 80% inhabit field (compared 60% controls) <2% clusters 10% controls). Compared controls, exhibit bluer UV-optical colours (indicating enhanced star formation) an AGN fraction...
We use Galaxy Zoo 2 visual classifications to study the morphological signatures of interaction between similar-mass galaxy pairs in Sloan Digital Sky Survey. find that many observable features correlate with projected pair separation; not only obvious indicators merging, disturbance and tidal tails, but also more regular features, such as spiral arms bars. These trends are robustly quantified, using a control sample account for observational biases, producing measurements strength...
