Is Terra Luna still active?

Hello there, I've been following the crypto world for quite some time, but recently I've noticed some mixed signals about Terra Luna. Could you please clarify for me if Terra Luna is still active? I remember it was quite popular not long ago, but I've also heard some rumors about its instability. Is it still operational and used widely in the crypto community? Or has it faced any significant challenges that might have led to its decline? I'm really interested in knowing the current status of Terra Luna and its future prospects, if any. Thank you for your time and assistance.
