Read about the history and future of Earth’s sun as well as fun facts about the sun’s age, size, temperature, and phenomena like solar flares.
A multi-scale path-planning method for large-scale scenes based on a framed scale-elastic grid map Yuekun Sun, Xiaochong Tong, Yi Lei, Congzhou Guo, Yaxian Lei, Haoshuai Song, Zige An, Jiayi Tang & Yibo Wu Article: 2383852 Published online: 09 Aug 2024 AbstractforA multi-scale path-...
Floodplain secondary channels have muddy banks and beds, are small relative to the main channel, and decrease in size over distance Active wood jams are prominent in secondary channels but are more abundant in channels connected to the river at both ends Flows exceeding the bankfull stage in the...
In this work, we describe a deep learning approach to map canopy-top height globally with high resolution, using publicly available optical satellite images as input. We deploy that approach to compute a global canopy-top height product with 10-m ground sampling distance (GSD), based on Sentine...
The seismological properties of Earth’s inner core are key to understanding its composition, dynamics and growth history. Within the inner core, fine-scale heterogeneity has previously been identified from backscattering of high-frequency compressional
we analyzed the orbits of the spacecraft in the HEEQ coordinate system [34], identifying the time intervals when the SolO located in the ecliptic plane approached the Sun–Earth line. The initial criterion of approaching was a distance from the spacecraft to the Sun–Earth line (see Equation...
The speed of the Earth's rotation varies from day to day. One of the main factors are the celestial bodies surrounding us. For example, the Moon's gravitational pull causes tides and changes the Earth's shape, ultimately resulting in a lower rotational speed. The distance between Earth and...
The Earth is approximately 93 million miles (150 million kilometers) from the sun, according to Space.com. At this distance, it takes about 8 minutes and 19 seconds for sunlight to reach our planet. 35. Something once collided with the moon (Image credit: NASA/GSFC) Many researchers think...
The Earth tides are caused by tidal forces in the Sun-Earth-Moon system44. The relative phase of the Sun and Moon cause the Earth to deform elastically. The effect of this deformation is a diurnal and semi-diurnal periodic variation in the distance between the crust and the centre of ...
Note that the labeled ddt measurements have been corrected for the small difference in the epicentral distance of the two doublet events, as indicated by the relative time shift between the outer-core BC and AB arrivals (Methods). The waveform plots and the notations follow the same style as...
