On March 12, 2025, the ESA Hera mission performed a flyby of Mars on the way to its target, the binary asteroid system Didymos-Dimorphos. This event provided a unique opportunity to acquire spectral data (within the 0.65-0.96 micron wavelength range) and high-resolution images of the far side of the Martian moon Deimos. The observations were

We present the SPECDIS value-added stellar distance catalog accompanying DESI Data Release 1. SPECDIS trains a feed-forward neural network (NN) with Gaia parallaxes and gets the distance estimates. To build up an unbiased training sample, we do not apply selections on parallax error or signal-to-noise (S/N) of the stellar spectra, and instead, we

Within 20 pc of the Sun, there are currently 29 known cold brown dwarfs—sources with measured distances and an estimated effective temperature between that of Jupiter (170 K) and approximately 500 K (ref. 1). These sources are almost all isolated and are the closest laboratories we have for detailed atmospheric studies of giant planets formed

Collisional impacts between asteroid-sized objects have been common throughout the history of our solar system and have significantly contributed to the formation of asteroid families (Nesvorný et al., 2015). Of particular interest are the low-albedo (geometric albedo < 0.10) and low-inclination (i ≤ 15°) asteroid families situated within the inner
